Structural and Optical Investigation of Transition Metal Oxide-Doped PbCl2-TeO2 Glasses

Abstract

Anahtar kelimeler AbstractIn the present study, structural and optical investigations of transition metal oxide (TMO)-doped tellurite glasses, which are promising glass matrices for opto-electronic applications due to their good non-linear optical properties and high semiconducting behavior, were realized. In the experimental studies, the effect of different transition metal oxides (Sb 2 O 3 , WO 3 , MoO 3 , Bi 2 O 3 , ZnO) on physical and structural properties of PbCl 2-TeO 2 glasses were determined and the changes in the infrared transmittance behavior of these glasses were investigated for different TMO-doped samples. For this purpose, physical investigation of glasses in the (2x)GMO-(25-x)PbCl 2 -(75-x)TeO 2 , x = 0 and 10 mol% (GMO: Sb 2 O 3 , WO 3 , MoO 3 , Bi 2 O 3 , ZnO) system was realized by determining the density, molar volume, oxygen molar volume, oxygen packing density, average cross-link density and number of bonds per unit volume values. It was found that the addition of transition metal oxides provide a more tightly packed network by decreasing the excess free volume with increasing the number of bonds per unit volume. Accordingly, the structural changes in the glass network were determined and the infrared transmittance properties of the glasses were evaluated running FTIR analysis. It was also detected that GMO-PbCl 2 -TeO 2 glasses show high infrared transmission in a wide infrared range. © Afyon Kocatepe Üniversitesi
