- 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/mm(2) value under high power blue radiant flux density of 19.1 W/mm(2). The results indicate that Y3Al5O12:Ce3+ CPP using nano phosphor can serve as a potential material for solid-state laser lighting in automotive applications.
