  Preparation technology, the structure determination, multiband luminescence
and nonlinear optical properties of the chalcogenide glasses are subject of
present work. The glass samples with two different Er content were prepared by
classical two-stage melt-quenching method. Glass state and morphology were
confirmed by X-ray and EDS techniques. Influence of the Erbium doping on the
luminescence and NLO properties was investigated.
