Abstract

An Al₂O₃/Y₃Al₅O₁₂:Ce³⁺ ceramic phosphor plate (CPP) for which a nano-phosphor is used for a high-power laser diode (LD) application for white automotive-lighting is reported here. The prepared CPP shows improved luminous properties that are owing to the light propagation of the hexagonal α-Al₂O₃ in the CPP. The amount of α-Al₂O₃ added to the Y₃Al₅O₁₂:Ce³⁺ CPP was optimized, and its impact on the luminous characteristics was investigated. The luminous properties of the Al₂O₃/Y₃Al₅O₁₂:Ce³⁺ CPP are improved when compared with the Y₃Al₅O₁₂:Ce³⁺ CPP, and the luminous emittance, as well as the conversion efficiency, is therefore also improved. The results of the present study indicate that the Al₂O₃/Y₃Al₅O₁₂:Ce³⁺ CPP can serve as a potential material for the solid-state laser lighting in automotive applications.
