Poduct Overview

Boron doped graphene quantum dots (B-GQDs) are nanomaterials obtained by introducing boron atoms into the structure of graphene quantum dots (GQDs). This doping significantly changes the electronic structure and chemical properties of GQDs, thereby expanding their applications in multiple fields.


Technical Parameter

Size<10 nm

Concentration: 10mg/ml (Max 100), solvent water

Luminous color: Blue light

Product Features

Electronic properties: Doping with boron enhances the conductivity of graphene quantum dots by introducing holes (p-type doping), resulting in better performance as electrode materials for supercapacitors and batteries.

Optical properties: B-GQDs exhibit improved light absorption and fluorescence properties, which are advantageous for optoelectronic devices and biological imaging applications. Its fluorescence performance is stable, the fluorescence quantum yield is high, and the fluorescence intensity remains relatively stable at different pH values and ion strengths.

Catalytic activity: The introduction of boron can alter the chemical activity of materials, making B-GQDs catalysts or catalyst carriers, exhibiting excellent performance in electrocatalytic processes such as oxygen reduction reactions (ORR).

Biocompatibility: B-GQDs have good biocompatibility and low toxicity, making them suitable for use in biomedical fields such as cell imaging.

Application Fields

Optoelectronic devices: B-GQDs have broad application potential in the field of optoelectronic devices, and their excellent optical and electrical properties make them ideal materials for photodetectors, solar cells, and other devices.

Biological imaging: Due to its good biocompatibility and low toxicity, B-GQDs can be used as fluorescent probes for labeling and imaging tumor cells, helping doctors diagnose and treat tumors more accurately.

Catalytic field: As catalysts or catalyst carriers, B-GQDs exhibit excellent performance in electrocatalytic processes such as oxygen reduction reactions and have broad application prospects.

Energy storage: The application of B-GQDs in supercapacitors and battery electrode materials has also received much attention, as their enhanced conductivity helps improve the performance of energy storage devices.

Be Aware - Highlighter Effect
The cooling effect is nice, but it leaves behind a pearlescent shine like a highlighter all over your eyes. It’s like you took highlighter and smeared it all over your eye area.

I can't put a pic of me with my eyes barely open and a big red note bigger than Rudolph's!!!!!
I tried this item because of the description given on the website, unfortunately, I had a bad reaction to one use of it and I ended up in the Emergency Room at my local hospital.....what a waste of $$$ for me, especially because it said it was all natural.....I have never had a reaction to anything I have put on my face before....I still have a big red nose and one side of my face/nostril is full.....

It feels refreshing
I applied the Dewyhour Eye Balm Cool Stick, and it instantly feels refreshing, almost like a menthol sensation. It’s very cooling and soothing on the skin. However, I recommend not applying it too close to your eyes, as the cooling effect can be a bit strong in that area. Overall, it works well to hydrate and refresh the under-eye area, and I love the silky texture it leaves behind!
