Abstract: | Visible photoluminescence (PL) was observed in binary g-As2S3, technologically modified g-GeS2(TiVj) and ternary glasses along (As2S3)x(GeS2)1-x line. PL maximum in g-As2S3 at 2.43 eV was assigned to band-to-band transitions and its position is in good agreement with value of optical band-gap edge absorption (Eo=2.4 eV). It is suggested that the peak at 2.2-2.3 eV in g-GeS2(TiVj) and GeS2-based ternary glasses may be attributed to presence of GeOx species. Complex PL peak at 2.6-2.7 eV in GeS2-based glasses was identified with germanium sulfur sites. |
