白光LED用Ce，Sm共掺杂YAG单晶荧光材料的光谱性能
Spectral Characteristics of Ce,Sm Codoped YAG Luminescent Materials for White-LED
摘要
Abstract
The growth and spectra characteristics of Ce doped Y3Al5O12（Ce：YAG） and Ce,Sm-codoped YAG（Sm,Ce：YAG） single crystals luminescent materials used for white light-emitting diode（LED） were investigated.The Ce：YAG and Sm,Ce：YAG single crystals were grown by the Czochralski method,and their luminescence properties were analyzed via the absorption,emission and excitation spectra.The results indicate that when Ce：YAG crystal is excitated by 460 nm blue light,a broad emission band of 480–650 nm range is produced in the absence of a red light component.It was found that the red light component of Ce：YAG luminescent ma-terial was of importance to improve the color rendering index,and this could be enhanced by Sm3＋ and Ce3＋ co-doping.The Sm,Ce：YAG crystal is promising to improve the color rendering index of white LED.关键词
