Optical spectra and energy level analysis of Dy3+:LaCl3

Abstract
The absorption spectrum of Dy3+:LaCl3 at 4 K has been photographed and measured from 20 000 to 38 000 cm1. Based on this and previous data, an empirical energy level scheme consisting of 151 observed crystal levels from 0 to 34 130 cm1 has been determined for the 4f9 ground configuration of trivalent dysprosium in LaCl3 crystals. An extended Hamiltonian with 20 adjustable parameters is used to fit by least squares the observed levels with a mean error of 6.9 cm1.
