WHITE LIGHT EMITTING PHOSPHOR AND LIGHT EMITTING MODULE USING THE SAME

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: Ba_4-x-y-zMg_xSi₂O₈: Eu_y, Mn₂ (0.7<=x<1, 0
