(上記一般式中、MはSr、BaおよびCaからなる群から選択される少なくとも1種であり、ZはEuおよびCeからなる群から選択される少なくとも1種の付活剤である。)

(上記一般式(2)中、MはSr、BaおよびCaからなる群から選択される少なくとも1種であり、ZはEuおよびCeからなる群から選択される少なくとも1種の付活剤である。)
上述したような酸化物蛍光体を還元/窒化することによって窒化物蛍光体が得られ、製造後の蛍光体は、その全ての部分が発光する。原料である酸化物蛍光体の窒化を制御した場合には、窒化物蛍光体と原料酸化物蛍光体との混合蛍光体を得ることもでき、近紫外、または青色発光ダイオードに塗布する際に必要な割合に製造することも可能である。混合蛍光体における組成比(窒化物蛍光体の重量/酸化物蛍光体の重量)は、例えば、焼成雰囲気(水素濃度等)、焼成条件(温度、時間等)を変化させることにより変化させることができる。例えば、雰囲気中の水素濃度が高い場合には、組成比は大きくなり、焼成温度が高い場合や焼成時間が長い場合も、組成比は大きくなる。
