    Abstract: 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.

    Abstract translation: 根据本发明的一个实施方案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＆amp; nlE; x＆lt; ll; 0.05,0.05＆nlE; y＆nlE; 0.5,0.001＆nlE; z＆nlE; 0.50，Re为稀土元素。 结果，当锶的浓度在0.05摩尔至0.5摩尔之间时，根据本发明的一个实施方案的荧光物质可以表现出在525nm和537nm之间的短波长。 此外，当铝的浓度高时，通过添加0.003摩尔至0.125摩尔的范围内的钡，荧光物质可以表现出在525nm和537nm之间的短波长。 此外，当铝的浓度高时，通过不仅添加AlN而且通过添加作为铝前体的Al 2 O 3来调节氧浓度，所以荧光物质可以表现出525nm至537nm之间的短波长。 最终，由于根据本发明的一个实施方案的荧光物质可以表现出525nm至537nm之间的短波长，因此可以防止色彩还原和显色指数的降低。

    Abstract: A complex crystal phosphor is an inorganic composition containing at least an M element, an Al element, silicon, oxygen, and nitrogen. The inorganic composition has particles having at least two types of crystal phase, and the at least two types of crystal phase include a first crystal phase which is the same as a M2SiO4 crystal and a second crystal phase as a β-sialon crystal. Here, M is at least one element selected from the group consisting of (Mg), calcium (Ca), strontium (Sr), and barium (Ba).
