Abstract

The deposited layers on glass surface with thickness between 230 and 500 nm were prepared by the chemical reactions of TeO2 and Sn during vacuum co-deposition, and were characterized as a function of the Sn/Te ratio between 0.5 and 2.8 by 119Sn conversion electron Mössbauer spectroscopy. The as-deposited samples showed amorphous character with very finely dispersed microstructure. The 119Sn Mössbauer spectra of as-deposited samples revealed the dominance of Sn(II) and Sn(IV) states although SnTe was also found when the Sn/Te ratio was high. A monotonous increase of the Sn(II)/Sn(IV) ratio was observed with increasing Sn/Te ratio.
