PHOSPHOR, PHOSPHOR PASTE AND LIGHT-EMITTING DEVICE

摘要

Disclosed are a phosphor, a phosphor paste and a light-emitting device. The phosphor contains a compound represented by the following formula (1). M13(1-x)Eu3xM2m M3nO3+m+2n (1) M1 represents at least one element selected from the group consisting of Ba, Sr and Ca; M2 represents at least one element selected from the group consisting of Mg and Zn; M3 represents at least one element selected from the group consisting of Si and Ge; and m, n and x respectively satisfy the following formulae: 0.9 <= m <= 1.1, 1. 8 <= n <= 2.2 and 0.00016 <= x < 0.003. The phosphor paste contains such a phosphor, an arbitrary organic binder and a solvent. The light-emitting device comprises such a phosphor and an arbitrary excitation source for the phosphor.
