Abstract
In work investigated with method IR of spectroscopy of amorphous selenium andsystem Se95As5 containing impurity samarium. It is certain that, in IR a spectrum of amorphous selenium due to hypervalent defects maxima with different intensity are observed in 230 and 270 cm-1.Increase of the concentration of impurity samarium in spectrum Se95As5, the maximum arises with 400cm-1frequency which, are connected with SmSe3 structural elements.
