で表される蛍光体の製造方法である。式(1)中、AはCaを示し、LはEuを示し、xは0.005<x<0.20、aは1.0≦a≦4.0、bは0.5≦b≦2、cは1.5≦c≦2.0、dは2.6≦d≦3.0を満たす数値を示す。
得られた蛍光体のPLE測定は、大気中室温雰囲気下で、励起光波長を変化させ、蛍光体からの発光ピーク波長をモニターして測定を行った。励起光波長に対するPLE強度(励起スペクトル)を図4中、破線で示す。蛍光体を励起可能な波長範囲は330nm近傍にピークを有し300〜500nmに及んだ。
得られた蛍光体のPL測定は、励起光として450nmを用いて、大気中室温雰囲気下で行った。得られた蛍光体のPL強度(発光スペクトル)を図4中、実線で示す。発光は520nm近傍にピークを有し、450〜600nmに及んだ。発光スペクトルの半値幅を図4から求めた。結果を発光ピーク強度と共に、表1に示す。
原料として、Ca3N25.18g、AlN8.77g、Al2O37.27g、Si3N45.00g、Eu2O30.38gを用いた他は、実施例1と同様にして、目的の(Ca0.97,Eu0.03)3Al6Si3O6N8の蛍光体を得た。得られた蛍光体について、実施例1と同様にして、PLE測定、PL測定を行った。図5に、励起光波長に対するPLE強度(励起スペクトル)を破線、PL強度(発光スペクトル)を実線で示し、発光スペクトルの半値幅を表1に示す。
比較例として、SrGa2S4:Euを用い、実施例1と同様にして、PLE測定、PL測定を行った。図6に、励起光波長に対するPLE強度(励起スペクトル)を破線、PL強度(発光スペクトル)を実線で示し、発光スペクトルの半値幅を表1に示す。
