In this study, Gd3+ and Bi3+ ions act to redshift the emission band to orange region, and to enhance significantly the maximum emission of YAG: Ce3+. On account that size mismatch between the host and the doped Gd3+ ion, the crystal structure turns soft, and the emission spectra are not tuned from 5...
