Abstract:
There are provided phosphors having high luminous efficiency at desired wavelengths and good light output stability and a light emitting device using the same. A phosphor according to an aspect of the invention includes a sulfide crystallographic phase and an oxide crystallographic phase. Here, the phosphor is a multiphase compound in which the sulfide crystallographic phase and the oxide crystallographic phase exist together.
