“…In the case of many tellurite glasses, their electrical, thermal, mechanical, optical, spectral and structural properties have been extensively investigated [1][2][3][4][5][6][7][8]. TeO 2 -based glasses have attracted more attention not only because of their numerous technical applications, but also because of their high glass-forming ability, wide transmission window, suitable glass stability, high refractive index, high nonlinear optical properties, low and accessible melting point and also no hygroscopic property (suitable ambient durability) which limits the application of phosphate glasses [1][2][3][4][5][6][7][8][9][10][11][12][13][14][26][27][28][29][30][31].…”

The glass transition of xSb-(60 -x)V 2 O 5 -40TeO 2 glasses with 0 \ x \15 (in mol%) at different heating rates (u = 3-12 K/min) has been studied using differential scanning calorimetry. The glass transition temperature (T g ) and crystallization temperature (T cr ) of these glasses have been determined. The effects of the heating rate and the Sb content on T g have been discussed. It has been observed that the transition region shifts to higher temperatures when the measuring time is reduced. The compositional dependence of T g has been determined and so an empirical equation has been deduced relating the glass transition temperature with the Sb concentration. Also, the value of glass-forming tendency has been studied for the present glasses.

“…The XRD studies have revealed the presence of Sb 2 4+ state and the redox ratio seems to be increasing with increase in the concentration of TiO 2 . The Raman spectral studies have revealed the presence of several conventional structural groups viz., TeO 4 , SbO 3 , BO 3 , BO 4 , TiO 4, TiO 6 in the glass ceramic network; these studies have also indicated a growing degree of disorder in the glass ceramic with increase in the concentration of TiO 2 . The experiments on PIB with 7 ns 1064 nm Nd:YAG laser beam indicated the maximum intensity of birefringence for the sample crystallized with 2.0 mol% of TiO 2 .…”

A family of antimony tellurite glasses of the composition (55‐x)TeO2‐10Sb2O3‐35B2O3 mixed with different concentrations of TiO2 (0 to 2 mol%) were prepared and crystalized. The samples were characterized by XRD and SEM techniques; spectroscopic (optical absorption and Raman) and PIB properties have been investigated. Randomly distributed crystals were identified by SEM. The XRD studies have revealed the presence of Sb2Te2O7, Sb2Te2O9, TiTe3O8,TiBO3 crystalline phases in these samples. The diffraction data also indicated that, the antimony ions coexist in Sb5+ state with Sb3+ state in these samples; however, the concentration of Sb3+ ions seems to be dominant over Sb5+ ions in the samples containing lower concentrations of TiO2. Optical absorption spectral studies have indicated that a considerable proportion of Ti ions do exist in Ti3+ state in addition to Ti4+ state and the redox ratio seems to be increasing with increase in the concentration of TiO2. The Raman spectral studies have revealed the presence of several conventional structural groups viz., TeO4, SbO3, BO3, BO4, TiO4,TiO6 in the glass ceramic network; these studies have also indicated a growing degree of disorder in the glass ceramic with increase in the concentration of TiO2. The experiments on PIB with 7 ns 1064 nm Nd:YAG laser beam indicated the maximum intensity of birefringence for the sample crystallized with 2.0 mol% of TiO2. This result combined with the optical absorption studies allowed us to conclusion that Ti ion surrounding ligands play principal role in the observed PIB effects (© 2011 WILEY‐VCH Verlag GmbH & Co.

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
