The energy location of 4 f and 5 d levels of trivalent lanthanide ions in LaF 3
Abstract
We performed theoretical calculations of the partial density of states for LaF3 crystals doped with Nd, Eu, Gd, Tb, Dy, Ho, Er, and Tm using hybrid exchange correlation functional PBE0 within the PAW formalism to find optimal energy positions of 4f and 5d levels of lanthanide ions.The positions of 4f and 5d energy states of Ln 3+ activators in the energy structure of LaF3 were analysed.An energy level diagram of 4f and 5d states of Ln 3+ ions in LaF3:Ln crystals (Ln = Ce,. . ., Lu) was constructed and comparatively analysed against the widely-used Dorenbos empirical model.
