Description
Summary:Abstract The research and development of orange‐emitting phosphor ceramics with excellent performance are significant for improving the optical quality of laser lighting and developing‐related emerging applications. For the first time, we prepared an orange‐emitting MgO–(Sr,Ba) 3 SiO 5 :Eu composite phosphor ceramic with high thermal conductivity, high thermal stability, and excellent luminescence properties. The thermal conductivity of the phosphor ceramic is as high as 32 W/(m K), and the luminescence intensity decreases by only 20% at 200°C, both of which are better than other orange‐emitting phosphor ceramics reported so far. The luminous efficacy of the phosphor ceramic (41.6 lm/W) is also close to the highest value of orange‐emitting phosphor ceramics until now. In addition, we also explored the application prospects of the composite phosphor ceramics in automotive turn signals and warm white laser lighting. This work provides inspiration for the preparation of other excellent orange‐emitting phosphor ceramics in the future.
