摘要： According to one embodiment of the present invention, a method for producing a sialon phosphor comprises: mixing a silicon precursor and an aluminum precursor and sintering the mixture to form a first sintered body; and mixing the first sintered body and a precursor for an active material and heat-treating the mixture to form a second sintered body. That is, the method for producing a sialon phosphor according to one embodiment of the present invention involves firstly forming the first sintered body serving as a host material to stably ensure a crystal structure, and then mixing the active material and the first sintered body so as to preserve the role of the active material without sacrificing the crystal structure of the first sintered body. Eventually, the active material in the crystal structure of the first sintered body is located in an empty sphere not located in the Si or Al position, thereby preventing the degradation of the crystallinity of the first sintered body. In addition, the crystal structure of the sialon phosphor produced by the above-described method is stable, and the sialon phosphor exhibits superior thermal stability at a high temperature, and therefore the degradation in the efficiency thereof caused by a shortened lifespan thereof is extremely slight even over long-term operation. In addition, the crystal structure of the sialon phosphor in the light-emitting device package comprising the sialon phosphor produced by the above-described method is stable, and therefore the degradation in luminance caused by a degradation of crystallinity may be prevented.

昂荧光体的制造方法中，首先，形成作为主体材料的第一烧结体，以稳定地确保结晶结构，然后将活性物质与第一烧结体混合以保持活性材料的作用而不牺牲第一烧结体的晶体结构。最终，第一烧结体的晶体结构中的活性材料位于不位于Si或Al位置的空球中，从而防止了第一烧结体的结晶性的降低。另外，由上述方法制造的赛伦磷光体的晶体结构稳定，并且赛隆荧光体在高温下表现出优异的热稳定性，因此由其寿命缩短导致的效率降低非常小即使经过长期的运作。另外，由上述方法制造的包含赛伦磷光体的发光器件封装中的赛隆荧光体的晶体结构是稳定的，因此可以防止由结晶度降低引起的亮度劣化。
