摘　　要：Nano-sized Er^(3+)∶Y_(3)Al_(5)O_(12)powders was successfully prepared via a simple sol-gel route at as low a temperature at 800℃whereas a temperature much higher is necessary to obtain this compound by solid state synthesis(about 1500℃).The phase purity,composition and microstructural features of the materials were analyzed by means of X-ray diffraction(XRD),infrared spectroscopy(IR)and transmission electron microscopy(TEM),and no other intermediate phase were observed to form in the range of 700~1000℃.The luminescence spectra of Er^(3+)substituted for Y^(3+)in YAG in 1%content was characterized on samples at different temperature.
