A light-emitting diode (LED) is a semiconductor diode that emits light when an electrical current is applied in the forward direction of the device, as in the simple LED circuit. LEDs are widely used as indicator lights on electronic devices and increasingly in higher power applications such as flashlights and area lighting.
The unique optical properties such as high photostability and narrow emission spectra of QDs can be exploited to synthesize solid state LEDs. Their emission color can be tuned from the visible throughout the infrared spectrum. This allows quantum dot LEDs to create almost any color. This provides more color options and better color rendering white LEDs. QD based LEDs are available in the same package types as traditional phosphor based LEDs.
NanoAxis synthesizes various multicolored (visible to NIR emitting) cadmium based (AxiCad) QDs with unique double layering (CdSe/CdS/ZnS) which would ensure their high photostability and reproducibility in terms of applications in LED.
