OXYNITRIDE PHOSPHOR, AND LIGHT-EMITTING DEVICE PACKAGE COMPRISING THE SAME |
摘要 |
PURPOSE: An oxynitride phosphor is provided to have excellent thermal performance and light efficiency, to have a small change even under high temperature and high humidity, and to obtain a white light emitting diode by a blue phosphor. CONSTITUTION: An oxynitride phosphor includes a crystal represented by chemical formula: : M_(3-x)A_2Si_3O_9N_2 : RE^(3+)_x where 0.01<=x<=0.3 and M is a trivalent metal. A light emitting diode(100) comprises a first semiconductor layer(122); a second semiconductor layer(126); an active material layer arranged between the first semiconductor layer and second semiconductor layer; a light emitting structure(120) emitting light with a main peak of 300-400 nm; and a phosphor layer(130) which is arranged on one side of the light emitting structure and generates light with a main peak of 400-550 nm. The phosphor layer comprises the oxynitride phosphor.
