摘要：

The Nd-doped yttrium aluminum garnet (Nd:YAG) nanocrystallites were prepared by the sol-gel method. The preparation technology for semi-transparent ceramics is described. Their structure and morphology were studied by XRD. The emission properties of Nd:YAG measured for nanopowders and ceramics are reported. In particular the spectra were measured as a function of excitation power. It was found that with increasing excitation power, there was increased emission from the F-4(5/2) state. The effect of grain size on luminescence properties was observed. (C) 2002 Published by Elsevier Science B.V.
