Samples of arsenic-rich AsSe glasses with the low content of limiting impurities are prepared; their transmission, Raman spectra and thermal properties are investigated. It is found that the As46Se54÷As50Se50 glasses do not crystallize during annealing and DSC analysis at a heating rate of 2.5÷10K/min, as opposite of the As40Se60 composition. For the first time, using a double crucible technique,...
