General description

Reactive group: Amine

Application

InP/ZnS core shell nanocrystals are Cadmium free/heavy metal free quantum dots suitable for different applications like light emitting diodes such as LEDs, displays, and biomedical applications. These Qdots are environmentally-friendly, heavy metal-free alternative to cadmium based quantum dots. These InP/ZnS core/shell quantum dots are non-toxic while offering high performance for various applications
