摘要：
The Photo luminescence (PL) spectra of Gd2O3:Eu composed of cubic and monoclinic structure were collected on November 2003 and June 2006, respectively. The results show that a portion of cubic Gd2O3 transforms into monoclinic after the sample was left as it is for two years; and the D-5(1)-F-7(J) emission of Eu3+ in cubic host was enhanced in this released complex. Considering the high pressure behavior of Gd2O3, we think this structural transition is due to the sample that endures a process of press and release while the residual stress is released slowly.
