摘要： According to one embodiment of the present invention, a phosphor has the following composition formula (1): [composition formula 1] Si(6-z)AlzOyN(8-z):Rex, where x, y and z are 0.018=x=0.3, 0.3=y=0.75, 0.42=z=1.0, respectively, and Re is a rare earth element. Therefore, a sialon phosphor of the present invention exhibits high luminance even when the aluminum concentration is 0.42 mol to 1.0 mol, and has a grain size D50 varying between 5 to 20 µm. In addition, a method for preparing a phosphor according to one embodiment of the present invention involves adjusting the oxygen concentration to ensure the superior crystallinity of the phosphor and thus improve the luminance thereof.

摘要： The fluorescent substance according to one embodiment of the present invention has the following compositional formula (1): [Compositional formula 1] SrySi(6-z)AlzOzN(8-z):Rex. Here, x, y and z are respectively 0.005 = x = 0.05, 0.05 = y = 0.5, 0.001 = z = 0.50, and Re is a rare earth element. As a result, the fluorescent substance according to one embodiment of the present invention can exhibit a short wavelength of between 525 nm and 537 nm when the concentration of strontium is between 0.05 moles and 0.5 moles. Also, the fluorescent substance can exhibit a short wavelength of between 525 nm and 537 nm by the addition of barium in a range of between 0.003 moles and 0.125 moles when the concentration of aluminium is high. Also, the fluorescent substance can exhibit a short wavelength of between 525 nm and 537 nm by adjusting the oxygen concentration by the addition not only of AlN but also of Al2O3 as an aluminium precursor when the concentration of aluminium is high. Ultimately, since the fluorescent substance according to one embodiment of the present invention can exhibit a short wavelength of between 525 nm and 537 nm, it is possible to prevent dropoff in colour reproduction and the colour rendering index.
摘要翻译：根据本发明的一个实施方式的荧光物质具有以下组成式（1）：[组成式1] SrySi（6-z）AlzOzN（8-z）：Rex。这里，x，y和z分别为0.005 = x = 0.05,0.05 = y = 0.5,0.001 = z = 0.50，Re是稀土元素。结果，当锶的浓度在0.05摩尔和0.5摩尔之间时，根据本发明的一个实施方式的荧光物质可以显示525nm和537nm之间的短波长。而且，当铝的浓度高时，通过加入在0.003摩尔和0.125摩尔之间的范围内的钡，荧光物质可以表现出在525nm和537nm之间的短波长。而且，当铝浓度高时，通过不仅添加AlN而且添加作为铝前体的Al 2 O 3，通过调节氧浓度，荧光物质可以表现出525nm和537nm之间的短波长。最终，由于根据本发明的一个实施方式的荧光物质可以表现出在525nm和537nm之间的短波长，所以可以防止颜色再现和显色指数的下降。
