ABSTRACT:
A fluorescent material is combined with a blue light-emitting diode or an ultraviolet light-emitting diode and consequently enabled to emit a white light. An oxynitride-based fluorescent material is formed by substituting Eu for part of M in a composition of MOSi2N2O, wherein M denotes one or more metals selected from among Be, Mg, Ca, Sr and Ba.
