Application

InP/ZnS core shell nanocrystals are Cadmium free/heavy metal free quantum dots suitable for different applications like light emitting diodes (LEDs; display; biomedical applications. The toxicity of Cd compounds and the corresponding regulations worldwide makes these InP/ZnS quantum dots as more desirable alternatives for consumer applications.
