Optical spectra of mixed anhydrous rare earth trihalides

The optical absorption spectra of 1 per cent Nd in LaCl 3 doped with Br and I have been investigated. Extra lines produced by replacing Cl ions by Br and I ions have been observed. Two contributions to the change of the energy of the absorption lines in different local environments can be separated;...

Description
Summary:The optical absorption spectra of 1 per cent Nd in LaCl 3 doped with Br and I have been investigated. Extra lines produced by replacing Cl ions by Br and I ions have been observed. Two contributions to the change of the energy of the absorption lines in different local environments can be separated; one which is due to the change of lattice spacing and another one which is due to the change of the ionicity of the anion.
