Abstract
A Ce3+-doped nitrodoagnesoaluminate Sr[Mg2Al2N4] phosphor was prepared from all-nitride precur- sors using gas pressure sintering method. The effective excitation by green light (510 nm) that revealed a broad emission from 550-650 nm prompted an innovation in the assembly of the pc-LED by using a blue chip LED that is sequentially coated with a green-emitting phosphor (β-SiAlON:Eu2+) that excites the upper Sr[Mg2Al2N4]:Ce3+ layer thereby producing white light. The use of this broadband emitting phosphor and the innovative configuration generates white light and puts forward two promising innovations for pc-LEDs.
