Abstract: front page image
(EN)Disclosed is an excellent orange or red phosphor which emits a high luminance light and does not decrease much in luminance when exposed to an excitation source. This phosphor contains a crystalline phase having a chemical composition represented by the following general formula [1]. (1 - a - b)(Ln'pMII'1-pMIII'MIV'N3)·a(MIV'(3n+2)/4NnO)·b(AMIV'2N3) [1] In the formula, Ln' represents a metal element selected from lanthanoids, Mn and Ti; MII' represents a divalent metal element other than the Ln' element; MIII' represents a trivalent metal element; MIV' represents a tetravalent metal element; A represents a metal element selected from Li, Na and K; and 0 < p ≤ 0.2, 0 ≤ a, 0 ≤ b, a + b > 0, 0 ≤ n, and 0.002 ≤ (3n + 2)a/4 ≤ 0.9.
