PHOSPHOR AND METHOD FOR PREPARING SAME |
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. |
