The chemical co-precipitation is used to prepare YAG:Ce3+ precursors, and B2O3-Al2O3-SiO2-Na2O is as the glass substrate,so the Ce3+-doped YAG glass-ceramic is fabricated,and then packaged into a glass-ceramic white LED.The photoelectric color parameters of the glass-ceramic white LED are measured by changing the substrate thickness and shape,and compared with those obtained by the conventional YAG phosphor coating method.The results show that the emission spectrum of the glass-ceramic white LED is essentia...
