Abstract

We report on Y₃Al₅O₁₂: Ce³⁺ ceramic phosphor plate (CPP) using nano phosphor for high power laser diode (LD) application for white light in automotive lighting. The prepared CPP shows improved luminous properties as a function of Ce³⁺ concentration. The luminous properties of the Y₃Al₅O₁₂: Ce³⁺CPP nano phosphor are improved when compared to the Y₃Al₅O₁₂: Ce³⁺ CPP with bulk phosphor, and hence, the luminous emittance, luminous flux, and conversion efficiency are improved. The Y₃Al₅O₁₂: Ce³⁺ CPP with an optimal Ce³⁺ content of 0.5 mol % shows 2733 lm/mm² value under high power blue radiant flux density of 19.1 W/mm². The results indicate that Y₃Al₅O₁₂: Ce³⁺ CPP using nano phosphor can serve as a potential material for solid-state laser lighting in automotive applications.
