发明名称 RED PHOSPHOR MATERIAL AND LIGHT-EMITTING DEVICE
摘要 A red phosphor material includes an essential component represented by a formula of A2-2xRxEuySmzLnx-y-zM2O8 as a main component, where A represents at least one selected from Ca and Sr; R represents at least one selected from Li, Na, and K; Ln represents at least one selected from La, Gd, and Y; M represents at least one selected from W and Mo; and x, y, and z are numerical values that satisfy 0.2≦x≦0.7, 0.2≦y+z≦0.6, 0.005≦z≦0.04, and x−y−z≧0. A light-emitting device includes an excitation light source and the red phosphor material that absorbs excitation light emitted by the excitation light source and emits red light.
