FAQs of Blue Luminescent Hydrophobic Graphene Quantum Dots (Powder):

Q: How should Blue Luminescent Hydrophobic Graphene Quantum Dots be stored to maintain their quality?

A: Store the GQDs powder in a cool, dry place, away from direct sunlight and moisture. Keep the product in its original sealed, double-layer vial under an inert atmosphere to preserve stability and ensure a shelf life of 1224 months.

Q: What is the optimal process for dispersing these quantum dots in a solution?

A: For best results, disperse the powder in non-polar solvents such as toluene, chloroform, or hexane. Their hydrophobic surface functionality promotes stable dispersion, while ultrasonication or gentle stirring can enhance uniform distribution.

Q: Where can Blue Luminescent Hydrophobic Graphene Quantum Dots be applied in research and industry?

A: These quantum dots are suitable for laboratory research, advanced materials synthesis, and R&D in applications such as bioimaging, photonics, optoelectronic devices, sensors, ink formulations, nanocomposites, and light-emitting devices.

Q: What are the primary benefits of using hydrophobically functionalized graphene quantum dots?

A: Hydrophobic surface groups enable excellent dispersibility in non-polar solvents, improving integration within hydrophobic matrices and nanocomposites. This enhances performance in specialized applications like optoelectronics and flexible sensors.

Q: When is UV excitation necessary and what wavelengths yield optimal blue luminescence?

A: UV excitation is required for photoluminescent experiments and applications. Optimal blue luminescence is achieved by exciting the quantum dots within the 350380 nm wavelength range, resulting in emission between 430460 nm.

Q: What safety precautions should be observed while handling this nanomaterial?

A: Although regarded as non-toxic for research purposes, it is important to follow standard nanomaterial handling protocols, including using gloves, protective clothing, and working in a well-ventilated area to avoid inhalation or direct skin contact.

Q: How customizable is the product packaging or lot size for bulk orders?

A: Lot sizes are customizable, ranging typically from 100 mg to 10 g per pack. The product is sealed in an inert atmosphere, double-layer vial to ensure integrity during storage and transport for various research and industrial needs.
