Energy transfer in Ce Nd and Yb co doped YAG phosphors

YAG-Ce, Nd, and Yb phosphors with a triple-doped system are prepared by conventional solid-state reaction method. The fluorescence emission and excitation spectra are measured and analyzed. The influences of Yb3+ doping concentration on the emission of Yb3+ and Nd3+ in YAG-Ce, Nd, and Yb are studied
