Strontium silicate-based phosphor, fabrication method thereof, and LED using the phosphor |
| 摘要 |
A strontium silicate-based phosphor, a fabrication method thereof, and an LED using the strontium silicate-based phosphor are provided. The phosphor is applied to a long wavelength ultraviolet LED, an active luminous LCD, etc., to enable an improvement in the color purity and to enhance the luminous efficiency. The strontium silicate-based phosphor is expressed by a chemical formula: Sr<SUB>3-x</SUB>SiO<SUB>5</SUB>Eu<SUP>2+</SUP><SUB>x </SUB>wherein x is 0<x<=1. The LED using the phosphor has a wide wavelength spectrum, shows a superior color purity characteristic, and can have a very high luminous efficiency as applied in the backlight source of an LED panel or an active luminous LCD.
