Abstract: Absorption and fluorescence spectra of Er(super 3+) (4f(super 11)) in crystals of NaBi(WO4)2 (NBW) is reported at temperatures between 15 K and room temperature. The quasi-center models has merit when used to calculate the crystal-filed splitting of the energy levels of the trivalent rare-earth ions in crystal hosts having a disordered structure.
