摘要：

Crystal-field parameters (B(k,m)) were obtained for LaOBr doped with Tm3+ from the analysis of luminescence spectra. The crystal-field Hamiltonian H(CEF) = SIMGA(km) B(km)+ SIGMA(i) C(km)(R(i)) for the C4v symmetry comprises five non-zero Bk,m parameters. The results of model crystal-field calculations in C4v symmetry for Tm3+ in LaOBr are compared with experimental data, for the lowest ten [S, L]J states 4f12 configuration. The set of crystal-field parameters (CFPS) calculated on the basis set of 54 sublevels reproduced the experimental level scheme within an RMS deviation of 11 cm-1.
