# Theoretical study on complex f-f transition simulation of luminescence spectra of nanocrystalline X$_1$-Y$_2$SiO$_5$:Eu3$^+$

Abstract : Based on the electrostatic crystal-field model of M. Faucher, in which the induced electric dipoles of ligands are obtained from a set of self-consistent combined equations and the contributions from far ligands are considered, the crystal-field energy parameters of nanocrystalline X-1-Y2SiO5:Eu3+ at two sites both with C-1 symmetry are calculated by using related data of its crystal structure and physical properties, Moreover, we successfully extend the above model to calculate the transition intensities, therefore giving a computed simulation of luminescence spectroscopy consistent with the experimental one which we measured before, supporting the model and the data we adopted here
