摘　　要：Re^3＋, Yb^3＋ co-doped （Re0005YbxY 0995 x ）3Al5O12 [Re = Ce, Er, x = 0, 0.02, 0.05, 0.1, and 0.2] transparent ceramics are synthesized by the solid state reaction and vacuum sintering as the down-conversion （DC） materials. The photoluminescence excitation and the photoluminescence spectra demonstrate the near-infrared quam turn cutting （QC） and the energy transfer （ET） from Re^3＋ to Yb^3＋ in both of these series of samples. The comparison of the near-infrared QC spectra of the two series of samples shows that the Ce^3＋, Yb^3＋ co-doped Y3Al5O12 transparent ceramic samples have much higher intensity of the emission spectra in the near-infrared region, and higher ET efficiency than the Er^3＋, Yb^3＋ co-doped ones. So, the Ce~＋, Yb3＋ DC ion pair is a better choice to imorove the efficiency of the crystalline silicon-based solar cells.Re^3＋, Yb^3＋ co-doped （Re0005YbxY 0995 x ）3Al5O12 [Re = Ce, Er, x = 0, 0.02, 0.05, 0.1, and 0.2] transparent ceramics are synthesized by the solid state reaction and vacuum sintering as the down-conversion （DC） materials.
