Description
Summary:The boundaries of the glass formation region in the ternary system La 2 O 3 –As 2 S 3 –Er 2 O 3 were found. Transparent glass of composition (La 2 O 3 ) 0.03 (As 2 S 3 )0.90(Er 2 O 3 )0.07 was studied by X-ray photoelectron and Raman spectroscopy. The intensities of the bands characterizing As–S, La–O, and Er–O bonds increased, and these bands were shifted toward higher energies. This was due to an increase in the covalence of these bonds and probably due to the formation of new bonds in the glasses. Samples in the glass formation region are resistant at 300 K to air, water, and organic solvents.
