Abstract:
A group of phosphor particles for a light-emitting device contains a plurality of types of phosphor particles having different emission peak wavelengths, while phosphor particles of a type having a relatively longer emission peak wavelength have a relatively larger median diameter as compared with phosphor particles of a type having a relatively shorter emission peak wavelength.
