Abstract: Phosphor-in-glass (PiG) color converter, being regarded as a good encapsulant material for long-lifetime high-powered white light-emitting-diode (LED), has developed rapidly in the recent years. However, it still remains a challenge to achieve fine chromaticity tuning of PiG for high-quality indoor lighting. Herein, a transparent garnet-based PiG was successfully prepared by introducing the Y 3 Mg 2 AlSi 2 O 12 :Ce 3+ orange phosphor and the Y 3 Al 4.6 Ga 0.4 O 12 :Ce 3+ green phosphor into TeO 2 -based glass matrix. The microstructure and luminescent properties of the PiG were investigated in detail. After optimizing the weight ratio of green phosphor to orange phosphor as well as the PiG thickness, facile chromaticity tuning to follow along Planckian locus in the thus-fabricated LED is achieved; correspondingly the correlated color temperature is adjusted from cool white to warm white. Hopefully, the developed garnet-based PiG is applicable in the long-lifetime color-tunable w-LEDs. [ABSTRACT FROM AUTHOR]
