| Abstract: LaOX:Sm3+ and LaOX:Nd3+ phorsphors were prepared and their fluorescence spectra measured at room temperature and liquid nitrogen temperature. Based on the Double Sphere Coordination Point Charge Field model, the assignments of the lines in the emission spectra of these phorsphors arc given, which reproduce the experimental spectra with a rms deviation of 22.6cm-1 and 29.7cm-1 for 4G5/2→ 6HJ(J=5/2,7/2,9/2)transitions of Sm3+ ion doped in LaOCl and LaOBr matrixes respectively. The influence of matrixes on crystal field effect of rare earth ions and other relevant questions arc dicusscd. |
