在单相磷光体中实现可调谐的颜色和白色光发射是一个具有挑战性的问题。采用高温固相法成功合成了一系列Ce 3 +-Eu 2+共掺杂的Ca 2Si 5 N8荧光粉。研究了样品的发光性质、能量传递和热猝灭特性。制备的Ca_（1.94）Na_（0.03）Si_（5 N）_（8：0.03）Ce（3+），y Eu（2+）（0.0000
Achieving tunable color and white light emission in a single phase phosphor is a challenging issue. Here, a series of Ce3+-Eu2+ co-doped Ca2Si5N8 phosphors were successfully synthesized by a high temperature solid state method. Luminescence properties, energy transfer (ET) and thermal quenching of the as-synthesized samples were investigated in detail. The emission color of as-prepared Ca1.94Na0.03Si5N8:0.03Ce(3+),yEu(2+) (0.0000
