摘要：
Structural and spectroscopic investigation of NaLaF4:Er3+ material at different doping concentrations is presented. X-ray diffraction patterns, up-conversion luminescence spectra and decay curves for H-2(9/2) -> I-4(15/2), S-4(3/2) -> I-4(15/2) and F-4(9/2) -> I-4(15/2) optical transitions in the material are shown and possible excitation routes are discussed. Raman spectrum for the uncloped material is presented and the effective phonon energy of the material is estimated. Based on the obtained results application of rare-earth doped NaLaF4 in the field of up-conversion phosphors is evaluated. (C) 2009 Elsevier B.V. All rights reserved.
