英文摘要Lu3Al5O12:Ce3+ is a promising color converter for laser diode (LD)-driven solid-state lighting due to the improved thermal stability of its luminescence compared with widely used Y3Al5O12:Ce3+ materials. However, LuAG:Ce3+ emits green light, which is a severe drawback for white lighting. Here, we report biphasic Lu3MgAl3SiO12:Ce3+ (BP-LMAS:Ce3+) transparent ceramics designed with a multiple-component strategy that exhibit red-shifted emission via the inclusion of a secondary phase (Lu/Mg)(4)(Al/Si)(2)O-9. This phase, dispersed homogeneously in the BP-LMAS:Ce3+ matrix, provides scattering centers, which improve the uniformity of the emitted light. The material demonstrates a broad orange-yellow emission centered at 564 nm (450-nm excitation), with an internal quantum efficiency of 76.1% and transmittance of 76% and enhanced thermal stability. Under the excitation of 14.5 W mm (-2) blue LDs, it generates white light with a high luminous flux of 5,655 lumen (lm). This demonstrates that BP-LMAS:Ce3+ transparent ceramics are promising candidates as color converters for LD-driven white lighting applications.
