Abstract
In this work, hexagonal boron nitride (h-BN) nanocrystals as functional additives in a phosphor-in-glass film are shown to substantially increase the luminous performance driven by a blue laser. Microstructural and spectroscopic studies reveal that h-BN particles distributed over the whole glass matrix build in situ a local heat conductive path which effectively accelerates heat dissipation and so greatly relieves the “thermal run-away effect”. The developed composite material with fine thermal manipulation may be a promising phosphor color converter for high-power-density laser-driven lighting.
