Description
従って、本発明の目的は、波長350〜430nmの光で励起させたときの発光強度が高く、熱に対する安定性が高い青色発光蛍光体を提供することにある。
(1)青色発光蛍光体の結晶格子歪みが、0.025〜0.080%の範囲にある。
(2)青色発光蛍光体が、透明材料に分散された状態で半導体発光素子の周囲に配置されている。
(3)上記(2)の透明材料に、さらに半導体発光素子にて発光した光で励起させると緑色を発光する緑色発光蛍光体と、半導体発光素子にて発光した光で励起させると赤色を発光する赤色発光蛍光体とが分散されている。
SrCO3粉末(純度99.99質量%、平均粒子径2.73μm)、SrCl2粉末(純度99.99質量%)、SrF2粉末(純度99.5質量%)、塩基性MgCO3粉末(4MgCO3・Mg(OH)2・4H2O粉末、純度99.99質量%、平均粒子径11.08μm)、SiO2粉末(純度99.9質量%、平均粒子径3.87μm)、Eu2O3粉末(純度99.9質量%、平均粒子径2.71μm)をそれぞれ、下記表1に記載のモル量にて秤量した。なお、各原料粉末の平均粒子径は、いずれもレーザー回折散乱法により測定した値である。
青色発光蛍光体とX線回折用標準試料[NIST(National Institute of Standards and Technology)のLaB6粉末]のX線回折パターンを測定する。測定条件は、X線回折装置:X’PertProMPD、スペクトリス(株)製、X線:CuKα、検出器:X’Clelerator(モノクロメータ付)、管電圧:45kV、管電流:40mA、測定範囲:2θ=20〜130度、ステップサイズ:0.0167度、発散スリット:1/2度固定スリット、走査速度:25.06度/分とする。
青色発光蛍光体と標準試料のX線回折パターンから、X線回折装置に付属のソフトウェア[X’Pert Highscore Plus(Ver2.2)]を用いて、Le Bail法により結晶格子歪みを算出する。
青色発光蛍光体に波長395nmの紫外光を照射して、発光スペクトルを測定する。得られた発光スペクトルの最大ピーク値を求め、これを初期発光強度とする。なお、表2中の値は、比較例1で得られた青色発光蛍光体の初期発光強度を100とした相対値である。
青色発光蛍光体を500℃の温度で1時間加熱した後、室温まで放冷する。放冷後の青色発光蛍光体に波長395nmの紫外光を照射して、発光スペクトルを測定する。得られた発光スペクトルの最大ピーク値を求め、上記の初期発光強度に対する百分率を算出し、これを発光強度維持率とする。
特開2009−280793号公報の実施例1に記載されている方法に従って、炭酸バリウム粉末、炭酸ストロンチウム粉末、酸化マグネシウム粉末、二酸化ケイ素粉末及び酸化ユウロピウムを、M3-aEuaMgSibO8の組成式において、MがBa0.26Sr0.74で、aが0.20、bが1.95となるように調合し、さらに塩化アンモニウムを、Mgを1モルとしたときに0.15モルとなる割合にて添加して混合し、大気雰囲気下1050℃で3時間仮焼し、冷却した。その後、2体積%水素−98体積%アルゴンの混合ガス雰囲気にて、1250℃の温度で9時間焼成して、組成M2.8MgSi1.95O8:Eu0.20(M=Ba0.26Sr0.74)の青色発光蛍光体を製造した。得られた青色発光蛍光体について、結晶格子歪みと初期発光強度を測定した。その結果を表2に示す。
