A PHOSPHOR PREPARED BY MIXING ALUMINUM GARNET AND SILICATE WITH THE ADDITION OF RARE-EARTH MEATERIALS

摘要

A phosphor comprising a mixture of aluminum garnet and silicate with the addition of rare-earth materials. The phosphor can be excited by light with a wide range of wavelengths, such as ultraviolet, near ultraviolet or blue, to produce white light useful for illumination. By adding rare-earth materials into the phosphor mixture a white light with a warmer color index is produced.
