Description
蛍光体を形成するZn、Ce、S、Si、Oの成分の内、Zn、Ce、Sの原子数の合計(3成分合計)を100としたとき、ZnとCeの原子数の合計が40.0以上、60.0以下とされる。ZnとCeの合計が40.0未満では、膜中のS量が多すぎるため、膜を作製することが困難になる。同様に、ZnとCeの合計が60超の場合も、膜中のZnあるいCeの金属成分が多すぎて、蛍光膜を形成することが困難になる。また、前記3成分合計に対するZnの原子数の比率が5.0以上、55.0以下とされ、Ceが0.5以上、55.0以下とされる。Znの比率が5未満でも、55超でも蛍光膜が得られ難くなる。上記のとおり、Ce比を調整することにより、発光色を制御することができるが、Ceの原子数の比率が0.5未満でも、55超でも蛍光膜が得られ難くなる。より好ましい範囲は、ZnとCeの合計が42以上、53以下であり、Znが10以上、50以下、Ceが10以上、50以下である。
蛍光体を形成するZn、Ce、S、Si、Oの成分の内、Zn、Ce、S成分の原子数の合計(3成分合計)を100としたとき、SiとOについては、Siの原子数の3成分合計に対する比率が5.0以上、100.0以下、Oの原子数の比率が8.0以上、120.0以下とされる。Siの比率が5.0より小さい場合も、100.0より大きい場合も蛍光膜になり難い。同様に、Oの比率が8.0より少ない場合も、120.0より大きい場合も蛍光膜になり難い。
