Photothermal performance of S@PiGF@A color converter and white laser lighting application. (IMAGE)
Caption
The reflective S@PiGF@A color converter prepared by thermocompression bonding can withstand high laser power density and enables a maximum LF of 6749 lm@47.70 W/mm2, which is 2.44 times higher than that of the PiGF@A color converter (2522lm@19.53 W/mm2). Increasing the thickness of sapphire can effectively reduce the operating temperature of the converter, thereby improving the phosphor conversion efficiency. The findings provide valuable guidelines to design high quality PiGF color converter for high brightness laser-driven white lighting.
