| 英文摘要 | Solid-state laser lighting (SSL) fabricated by integrating laser diode with phosphor is a new development to achieve high luminance. Because of the high temperature caused by the laser, the phosphor conversion apparatus is demanded to possess excellent thermal properties. In this paper, we utilized spark plasma sintering (SPS) to prepare the Al2O3-YAG:Ce phosphor ceramics with outstanding performances. Due to the high thermal conductivity and high transmittance, a high saturation input power (32 W/mm(2)) can be achieved for the sample with the lowest porosity. The correlated color temperature (CCT) and color rendering index (CRI) of composite ceramics with the lowest porosity are stable as the input power increases from 0.7 W/mm(2) to 30.8 W/mm(2) . Nevertheless, the sample with the highest porosity shows the highest luminescence efficiency (305 lm/W) and luminous emittances (1796 lm/mm(2)), which can be ascribed to the scattering of the pore.
