Method for treating surface of phosphor, phosphor, light-emitting device, and illumination device |
| abstract |
Provided are a method for treating the surface of a (Sr,Ca)AlSiN 3 nitride phosphor that can improve the moisture-resistance reliability thereof without deterioration in optical properties, a phosphor, a light-emitting device, and an illumination device. The surface of a phosphor is treated in an immersion step of immersing a phosphor of which the host crystal has a crystal structure substantially identical with that of (Sr,Ca)AlSiN 3 crystal in an aqueous ammonium phosphate-containing solution (Step 1 ) and a heat-treating step of leaving the phosphor after the immersion step in an environment at a temperature of 250 to 550° C. for 2 to 24 hours (Step 2 ). |
