Fabrication and luminous properties of phosphor ceramic for application in automotive laser headlight
Current Applied Physics(2020)
摘要
We report on the optimization of fabrication of a ceramic phosphor plate (CPP) using α-Al2O3 as functional materials for an automotive laser headlamp. The prepared CPP shows the high luminous characteristics with increasing α-Al2O3 contents because of the light scattering of the hexagonal structure of α-Al2O3 materials. We investigated the correlation between α-Al2O3 and thickness of CPP. The luminous properties of the CPP are improved and optimized according to the variables of one. We found that the prepared sample is a potential material for future solid-state laser lighting in application as an automotive headlamp.
