摘要:
This invention provides a phosphor capable of emitting a white light by itself and a light emitting module using the phosphor. A white light emitting phosphor is represented by the following formula, and it is preferable that an excitation peak wavelength may be in a range of 350 to 420 nm: Ba4-x-y-zMgxSi2O8: Euy, Mn2 (0.7≦x
