| 简介 |
A light emitting device includes a light emitting element 1 that has a light emission peak wavelength in a range from 300 nm to 530 nm, and a phosphor 2 that absorbs light from the light emitting element 1 and converts the wavelength of the light to emit light with a light emission peak wavelength different from the light emitting element. The phosphor is represented by the general formula M15−xEuxM2mM3nO2m+(3/2)n+5 where x, m and n fall within ranges 0.0001≦x≦0.3, 1.0≦m≦2.5 and 0≦n≦2.5, M1 is at least one element selected from the group consisting of Mg, Ca, Sr, Ba and Zn, M2 is at least one element selected from the group consisting of Si, Ge and Sn, and M3 is at least one element selected from the group consisting of B, Al, Ga, In and rare earth elements. |
