Product Overview

Carbon quantum dotsCQDs are quasi spherical amorphous carbon nanocrystals composed of sp2 and sp3 cluster carbon structures, surrounded by abundant oxygen-containing functional groups such as hydroxyl, carbonyl, carboxyl, etc. Their main constituent elements are C, H, O, and N. The luminescence mechanism of CQDs can be mainly attributed to these three types: quantum confinement effect, surface state luminescence, and molecular state luminescence. Carbon quantum dots are composed of C=C and C-C bond cores that are prone to π→π * transitions, as well as various organic molecular functional groups distributed on the surface that are prone to n →π * transitions. The structure and composition of carbon quantum dots result in strong absorption of short wavelength light waves in the ultraviolet range (260-320 nm), accompanied by low-intensity absorption of visible light (400-710 nm).

The preparation methods of carbon quantum dots are divided into top-down method and top-down method. The top-down method is to cut large-sized carbon structural materials through physical or chemical methods, mainly including arc discharge, laser ablation, ultrasonic treatment, and chemical oxidation. The bottom-up approach is to aggregate small molecule precursors into large-sized CQDs through chemical reactions, mainly including water/solvothermal, template method, microwave-assisted, and solid-phase methods.

Hydrophobic carbon quantum dots are a special type of carbon quantum dot. Compared with common hydrophilic carbon quantum dots, their surface chemical groups or modifications make them less soluble in aqueous phase, while they have better solubility in non-polar or weakly polar organic solvents. More suitable for dispersion and application in non-polar solvents such as DMF, toluene, n-hexane, chloroform, etc.

Product Features

 

Surface characteristics: The functional groups on the surface are mainly hydrophobic, such as long-chain alkyl groups, aromatic rings, etc., which make them difficult to disperse in aqueous phase, but have good solubility in non-polar organic solvents.

Optical properties: It has unique light absorption and emission characteristics, and its fluorescence emission wavelength may vary due to different preparation methods and surface modifications. Compared to hydrophilic carbon quantum dots, their optical properties may be relatively insensitive to changes in environmental polarity.

Stability: Due to the presence of hydrophobic groups on the surface, it may have better chemical and thermal stability in some organic solvents.


Application Fields

 

 

Organic light-emitting diode (OLED): As a material for the light-emitting layer, its hydrophobicity helps to better integrate with other organic layers, improving the device's luminous efficiency and lifespan. For example, in multi-layer structured OLEDs, hydrophobic carbon quantum dots can improve charge and energy transfer processes, thereby enhancing luminescence performance.

Organic photovoltaic devices: used to improve the light absorption and charge separation efficiency of photovoltaic materials. For example, incorporating it into organic semiconductors to improve their photoelectric conversion performance.

Organic catalysis: can participate in organic reactions as a catalyst or co catalyst. For example, in some hydrogenation reactions, hydrophobic carbon quantum dots can promote the progress of the reaction and improve selectivity.

Biomedical applications: Although hydrophobicity limits its direct in vivo application, it can be used to construct nanocarriers with specific functions. For example, by combining with hydrophobic drugs, drug encapsulation and controlled release can be achieved.

Sensor: used to detect specific substances in organic solvents. For example, detecting the concentration of organic pollutants or chemicals in non-aqueous systems.

Sheets are good. Greens don't match
Color: 08 - Sage Green, Size: King (20" X 36"), Color: 08 - Sage Green, Size: King (20" X 36")
I purchased the sage green sheets to go along with another Bedsure comforter, then purchased 2 more pillow cases (because i I like a lot of pillows) and the greens don't exactly match. This doesn't REALLY bother me as I feel like its fine with a little "texture." Sheets feel nice and light and I love the look of it in my room.

Good buy Pillowcases
Color: 08 - Sage Green, Size: King (20" X 36")
I bought these Bedsure king-size pillowcases from Amazon and overall I’m very happy with them. The first thing I noticed was how incredibly soft and smooth the fabric feels. They almost feel silky, which makes them very comfortable to sleep on. When you lay your head down, the material feels cool and gentle on the skin, which I really like. I also appreciate the zipper closure. It keeps the pillow securely inside the case and makes everything look neat and tidy on the bed. The zipper is hidden well and doesn’t feel bulky or uncomfortable. The only small downside is that the pillowcases are so smooth that the pillows can sometimes slide around or even slip off the bed a little. However, that’s really just because the material is so silky. Overall, I would still recommend these pillowcases. They are soft, comfortable, and feel like a nice upgrade compared to regular pillowcases.

Very nice pillowcases
Color: 06 - Beige, Size: Standard (20" X 26")
These pillowcases are really nice. They're soft and wash well. I really like the pocket on the end. It makes your pillows look nice and neat. The price is good too.

Love the sheets but GOSH THEY STINK
Color: 19 - Forest Green, Size: Queen (20" X 30")
I have the dark green sheets and bought these for extra cases to match. I would give them 5 stars if it weren’t for the fact that they smell absolutely horrible. I am so surprised after reading reviews that more people don’t mention it?! Maybe it’s more prominent in darker colors but I have washed these now 3 different times even with scent beads and still hate the smell. I wish I could accurately describe what it smells like— it’s just not good and for some reason, body heat only exacerbates it and makes the smell even worse and I wake up feeling like a smell like the sheets… which isn’t a good thing. Besides that, I do really enjoy them. They feel great on your skin and I love the color. I wish the smell didn’t kill them so badly for me ☹️

Comfy soft pillow covers
Color: 02 - White, Size: Queen (20" X 30"), Color: 02 - White, Size: Queen (20" X 30")
Absolutely love these pillow cases! I bought 2 sets. After I received them & washed & dried them they did remain wrinkly. I just went ahead and put them on my pillows & the wrinkles went away. I continue to love the feel, coolness & comfort. Will definitely buy more.
