As the most commonly used color phosphor in w-LEDs, Ce: Y3Al5O12 (Ce: YAG) makes an almost perfect match with blue chips to convert blue light into yellow light and obtain white light. But unfortunately, the deficiency of the red component in the mixed white light makes the light quality too poor to meet the standards of modern lighting. The redshift of Ce3+ emission in Ce: YAG is of high interest to industry and researchers.
