FAQs of LED Quantum Dots:

Q: How can I customize the emission wavelength of LED Quantum Dots?

A: You can request a custom synthesis tailored to your desired emission wavelength within the 400 nm to 700 nm range. The emission can be precisely adjusted by altering the diameter of the quantum dots during production.

Q: What applications are LED Quantum Dots best suited for?

A: LED Quantum Dots are widely used in display panels, LEDs, bio-imaging, sensors, and lighting systems, providing vivid color output, high efficiency, and enhanced visual performance.

Q: When should quantum dots be handled in a fume hood and with PPE?

A: Quantum dots, especially those with cadmium-based cores, should always be handled in a fume hood while wearing personal protective equipment to minimize exposure to potential toxicity.

Q: Where should I store LED Quantum Dots for optimal shelf life?

A: Store LED Quantum Dots in a cool, dry place away from light and moisture. Adhering to recommended storage conditions extends shelf life to 1224 months.

Q: What is the process for dispersing these quantum dots in solvents?

A: Quantum dots with oleic acid, TOPO, or custom ligand capping exhibit high dispersibility in compatible organic solvents such as toluene, chloroform, and hexane. Simply mix as directed to ensure uniform suspension.

Q: What are the benefits of choosing InP-based quantum dots?

A: Indium Phosphide (InP)-based quantum dots are lead-free, offering a safer alternative for environments with strict toxicity regulation, while still delivering high quantum yields and stable performance.
