IR, UV–vis spectroscopic and DSC investigations of europium doped tellurite glasses obtained by sol–gel synthesis
Journal of Physics and Chemistry of Solids(2013)
摘要
FTIR, UV–vis spectroscopy and DSC studies were utilized in order to study structural changes produced by the variation of the Eu(NO3)3 content in binary europium–tellurite glasses obtained using the sol–gel method. Our results show that the europium ions can be considered as modifiers because they will produce the transformation of [TeO4] and [TeO6] structural units into [TeO3] trigonal pyramidal units and the formation of a significant number of non-bridging oxygen ions.
