| Resumen en inglés | In this work, radiofrequency sputtered CdTe oxide (CdTeO) films with different oxygen contents were studied by Raman spectroscopy. In films with oxygen contents minor than 0.37 at., we observed bands associated with the LO and 2LO modes of CdTe. As oxygen content increases up to 0.60 at., they appear bands related with [TeO3] -2 trigonal pyramids and with [TeO4] -4 trigonal bipyramids, similar to those reported by other authors in metal-oxide doped TeO2 glasses. Some additional peaks beyond 750 cm-1, that we have related with [CdO6] - polyhedra and with CdxTeyOz compounds, were observed in that films. We conclude that films evolve from crystalline CdTe to a glassy material where a mixture mainly composed of Te, Cd-Te, [TeO3] -2 and [TeO4] -4, structural units is formed as the oxygen content in the films increases from 0.15 at. to about 0.60 at. fraction |
