LED Lighting:

LED (Light emitting diodes) Lighting is an energy saving option and contributes to the fight against global warming and environmental pollution cause by mercury present in the traditional fluorescent lamps.

White LEDs for general lighting:

White LEDs are commonly produced by coating phosphors onto LED chips

LED Phosphors:

LED Phosphors are luminescent materials that convert Ultra-violet (UV) or blue LEDs into white light. The most common commercial white LEDs are produced by using blue LED chips coated with a yellow phosphor.

Phosphors are further used to fine tune the type of white light produced by LEDs, i.e., cold white  or warm light.

The problem:

Most of the commercial LED phosphors in the market today contain critical rare-earth materials which are facing high supply risks due to geopolitical reasons. Their production also polutes the environment.
