YELLOW PHOSPHOR AND WHITE LIGHT EMITTING DEVICE USING THE SAME

摘要

The invention relates to yellow phosphor with a red wavelength region thereof reinforced and a white light emitting device incorporating the same. The yellow phosphor has a formula of M_x(Al, Ga)₅O₁₂:Ce_y,Eu_z, in which M is at least one selected from a group consisting of Tb, Y, Gd, La and Sm, where 2.4<=x<=2.998, 0.001<=y<=0.3 and 0.001<=z<=0.3.
