Abstract

Pr3+,Ce3+:YAG crystal fibers were grown by laser heated pedestal growth method as the white LED materials.The Luminescence properties of the materials was investigated,and the results show that in Ce3+ ions and Pr3+ ions codoped fluorescence emission process the Pr3+ ions 610 nm fluorescence intensity can be increased by Ce3+ ions sensitization. High efficient white LED was gotten by combined Blue LED and grown Pr3+,Ce3+:YAG crystal fiber. The white LED was improved with the CIE color coordinates (x＝0.322, y＝0.335) and 84.3 of the CRI. It can be used for high effient power white LED in future.
