Abstract

Phosphor is a key component in the recent advances in lightemitting diodes It converts the light emitted by ultraviolet or blue LEDs into visible light In the past decade scientists and researchers have developed various phosphors for general illumination and optical displays and they continue to develop new phosphors for wLEDs in order to overcome conventional lighting systems The phosphors should have strong absorption of the light emitted by the UVLEDs and be able to efficiently downconvert it into longer wavelengths ie visible light Among the number of developed phosphors silicate borate phosphate and nitridebased phosphors for have been studied for UVLED applications This chapter will discuss novel phosphors for UVLEDs according to their chemical compositions and their pertinent applications in white light‒emitting diodes
