Abstract
The white LED was fabricated using a mixture of phosphors (LuAG: Ce and CaAlSiN3: Eu) in bismuthate glass as converted materials. The phosphors (LuAG: Ce and CaAlSiN3: Eu) in glass was prepared by low-temperature co-sintering. The microstructure and luminescent mechanism of a mixture of phosphors (LuAG: Ce and CaAlSiN3: Eu) in glass was investigated, the results showed that phosphors (LuAG: Ce and CaAlSiN3: Eu) not only exist in the glass matrix without noticeable reaction, but also can be effectively excited by blue light. After simply varying the weight ratio of bismuthate glass to phosphors (LuAG: Ce and CaAlSiN3: Eu) as well as the ratio of LuAG: Ce to CaAlSiN3: Eu, the CIE chromaticity tuning in the fabricated LED has been achieved. It has revealed that the fabricated white LED has excellent developing potential for different lighting applications.
