Light-emitting diodes or LEDs are increasing their share as components in lighting and display markets on a daily basis. In this article, an overview is given of the scientific research that is still going on to improve the quality of the end products and to lower the price as much as possible. It is dwelled upon how white LEDs are constructed from a semiconductor diode and one or multiple photoluminescent materials or phosphors. Different applications require different specifications for white LEDs, implying the need for a dedicated design strategy of the optical materials forming the key components of a white LED.
