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.

Shelves
Color: Rustic Brwon, Size: 16in
Love the quality but got the wrong color. Company was easy to work with in return. If you need shelving these are awesome

There are better floating shelves
Color: Rustic Brwon, Size: 16in
Doesn’t feel very sturdy like other floating shelves I’ve bought, and they slant a little. The anchors and screws that it came with all broke so we had to get our own for it to feel more secure on the wall, but still feels wobbly. Overall, it looks good on the wall after the fact, but won’t be adding too much weight on it.

Excellent privacy shade.
Color: Coal Black
This delivered on exactly what it promises. So happy with the quality for the value. The shades are a fabric, nylon like, that are attached with a pocket on one end and velcro that adheres around the bar on the other. This was incredibly easy and straightforward to put together. Every piece was clearly labeled, coordinated with the instruction sheet, and fit perfectly. Honestly, I wasn’t planning to leave a review but I was so impressed by how clearly labeled and well explained the instructions were that I felt compelled to note it. Especially for anyone who doesn’t like putting things together, or is used to subpar instructions, this is leagues above the rest. It’s such a simple build anyway, but after buying so many things that barely fit as they should, this stands out. It is lightweight and easy to move. Offers privacy when opened, then can be folded out of the way. It looks exactly as pictured. No complaints, it’s a solid item and worth the price.

Decent quality for the price
Color: Grey
Decent quality for the price. Other privacy screens were extremely out of my budget, but this looks and works just fine- I just needed something simple to place behind my couch to hide some clutter. It took me about a half hour to assemble, but it was easy enough. It might be due to my carpeting, but I don't trust that the screen would be stable enough to stand freely without falling. Thankfully my plan all along was to wedge the screen between the couch and a box of clutter anyway, so for me it works as l'd planned!

Overpriced but effective.
Color: Cream
I happened to get lucky and get a warehouse deal at an additional 30% discount. Even at $25, it feels a little overpriced. But it was easy to assemble and serves its purpose. If you line the Velcro up exactly, the panels sag, if you stretch past even, but where it still grips, they look pretty ok. It is very light and does fold very compact for easy storage.
