Facile synthesis of a thermally stable Ce super(3+):Y sub(3)Al sub(5)O sub(12) phosphor-in-glass for white LEDs
This study outlines a general but convenient approach towards the synthesis of a Ce super(3+):Y sub(3)Al sub(5)O sub(12) phosphor-in-glass (PiG) with a relatively low sintering temperature. A comparative study of the as-synthesized PiG and glass ceramic prepared using a conventional route was carrie...

| description | This study outlines a general but convenient approach towards the synthesis of a Ce super(3+):Y sub(3)Al sub(5)O sub(12) phosphor-in-glass (PiG) with a relatively low sintering temperature. A comparative study of the as-synthesized PiG and glass ceramic prepared using a conventional route was carried out to explore the structural, morphological and optical properties. In addition, the effect of phosphor concentration and the sintering temperature/time on the luminescence properties was systematically investigated. Notably, we fabricated a high-performance white LED based on PiG with a high luminous efficacy (125 lm W super(-1)), low correlated colour temperature (4329 K) and colour rendering index of 68. Furthermore, the PiG material demonstrates an excellent thermal stability up to 150 degree C, superior to the low thermal stability of conventional Ce super(3+):Y sub(3)Al sub(5)O sub(12) doped silicone. Therefore, we present a transparent phosphor glass with desirable potential for application in high powered W-LEDs. |
