The present invention relates to a production method for oxynitride or nitride phosphor powders which can be used in displays such as vacuum fluorescent displays (VFDs), field emission displays (FEDs) and LED display devices, or in lighting devices such as cold cathode fluorescent lamps (CCFL) and LED lamps, or in light-emitting apparatuses such as back-lights, wherein the production method for phosphor powders comprises the step of subjecting part or all of a metal oxide to nitriding by calcining in an atmosphere containing nitrogen, using a fine carbon substance.
本发明涉及一种可用于显示器(如真空荧光显示器(VFD)、场发射显示器(FED)和 LED 显示设备)或照明设备(如冷阴极荧光灯(CCFL)和 LED 灯)的氧
氮化物或
氮化物荧光粉的生产方法、或背光灯等发光装置中,其中荧光粉的生产方法包括使用细碳物质在含氮气氛中通过煅烧使部分或全部金属氧化物氮化的步骤。
