a PLE and PL spectra of YAG:Ce-PGC and YAG:Ce powder. b Internal/external quantum efficiency (I/EQE) and absorption efficiency (AE) of YAG:Ce-PGC. IQE (AE) of YAG:Ce powder was determined to be 99.4% (74.5%). c Schematic diagram of laser driven light source test system. A 450 nm blue laser is emitted from the laser source and irradiated onto the sample using two optical focusing mirror. The light emitted by the sample and the reflected blue laser are then collected using an integrating sphere and analyzed within the fiber optic spectrometer. d Luminous flux and e the luminous efficacy of YAG:Ce-PGC with different concentrations as a function of the laser power density. f Photostability of the YAG:Ce-PGC, commercial YAG:Ce phosphor in glass (YAG:Ce-PiG), and YAG:Ce phosphor in silicone resin (YAG:Ce-PiS) under 2 W mm−2 blue laser irradiation. Source data are provided as a Source Data file.
