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： 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, even when the aluminum concentration is 0.42 mol to 1.0 mol, a sialon phosphor of the present invention exhibits high luminance and has a particle 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.
