Description
Ln源化合物としてY2O3;1.44モル、M源化合物としてγ−Al2O3;2.5モル、Ce源化合物としてCeO2;0.09モル、Tb源化合物としてTb4O7:0.0
075モル、並びに融剤としてBaF2;0.25モルを用い、1400℃で焼成したこ
と以外は実施例1と同様の方法にて、黄色発光蛍光体(Y0.96Ce0.03Tb0.01)3Al5O12を作製した。得られた蛍光体につき、実施例1と同様に物体色と全光束を測定したところ、物体色はL*=102.7、a*=−14.9、b*=58.8、全光束は116%
であった。結果を表−1に示す。
(実施例6)
Y 2 O 3 as the Ln source compound; 1.44 mol, γ-Al 2 O 3 as the M source compound; 2.5 mol, CeO 2 as the Ce source compound; 0.09 mol, Tb 4 O 7 as the Tb source compound : 0.0
075 mol, and BaF 2 as a flux; with 0.25 mole, in the same manner as in Example 1 except that calcined at 1 400 ° C., the yellow-emitting phosphor (Y 0.96 Ce 0.03 Tb 0.01) 3 Al 5 O 12 was produced. When the object color and the total luminous flux were measured for the obtained phosphor as in Example 1, the object color was L * = 102.7, a * = − 14.9, b * = 58.8, the total luminous flux. 116%
Met. The results are shown in Table-1.
(Example 6)
Ln源化合物としてY2O3;1.44モル、M源化合物としてγ−Al2O3;2.5モル、Ce源化合物としてCeO2;0.12モル、並びに融剤としてBaF2;0.25モルを用い、1400℃で焼成したこと以外は実施例1と同様の方法にて、黄色発光蛍光
体(Y0.96Ce0.04)3Al5O12を作製した。実施例1と同様の評価を行ったところ、物体色はL*=101.2、a*=−14.7、b*=57.8、全光束は110%、温度特

(実施例7)
Y 2 O 3 as the Ln source compound; 1.44 mol, γ-Al 2 O 3 as the M source compound; 2.5 mol, CeO 2 as the Ce source compound; 0.12 mol, and BaF 2 as the flux: 0 with .25 mole, in the same manner except that calcined at 1 400 ° C. as in example 1 to prepare a yellow-emitting phosphor (Y 0.96 Ce 0.04) 3 Al 5 O 12. When the same evaluation as in Example 1 was performed, the object color was L * = 101.2, a * = − 14.7, b * = 57.8, the total luminous flux was 110%, and the temperature characteristic was 98%. It was. Moreover, t1 was 151 ns and t2 / t1 was 2.03. The results are shown in Table-1.
