Abstract = 'For chalcogenide glasses in the system (1 - x)0.15Ga2S i90003 0.85Gha sido2 圎r2S i90003, the intake and luminescence spectra are usually investigated and thé X-ray diffraction analysis is carried out.
The likelihood of describing the reliance of the strength of erbium Iuminescence on its concentration using the previous suggested formula has happen to be discussed. A small shift in the place of the erbium absorption music group with the raise of its content in the glass shows the decrease of the effective cost on it, while the minimal changes in the position place of the 1st razor-sharp diffraction top factors to the constancy of the cup's intermediate-ordér parameter. For chalcogenide glasses in the system (1 - x)0.15Ga 2S 3 0.85GeS 2 圎r 2S 3, the absorption and luminescence spectra are looked into and thé X-ray diffraction analysis is performed.
