The light-emitting diode (LED) materials have undergone significant growth due to the increasing need for more efficient illumination technologies, and because of the constant innovation in the LED sector. LEDs are semiconductor devices in which illumination occurs when an electric current passes through them – and are thus highly more effective and efficient than the lighting technologies employed in the incandescent and fluorescent categories. The need for high performance LEDs’ materials such as semiconductors, phosphors, and encapsulants has been pushed higher by demand for the LED lighting solutions because of the need to cut down on global energy use and emission of green house gases.
