The role of SrO on structural and spectroscopic features of SAT samples have been investigated. In order to generate crystalline phases having nano scale, glass samples were exposed to controlled heat treatment at 460 °C for 8hrs. X-ray diffraction (XRD) confirms non-crystalline structure for SAT glass samples whereas, crystalline phases i.e., Te₄Sr₃O₁₁, α–TeO₂, and Claudetite (As₂O₃) were identified in glass ceramic samples with crystallite size ranging from 25 to 58 nm. Structural disorder in glass matrix showed a significant role in mechanical and physical properties of glass samples at varying SrO concentration (10–30 mol%). The density decreases monotonically with increase in SrO concentration, which could be due to substitution of higher molecular weight As₂O₃ with a lower molecular weight SrO, that results in a decrease in the composition's net molecular weight. Further, thermal parameters were increased monotonically such as, glass transition temperature (T_g∼353→425°C), on-set crystalline temperature (T_õ_∼378→492°C), and peak crystalline temperature (T_p∼405→506°C). Increased optical parameters were also observed with optical band gap (E_g∼2.215→3.179eV), Urbach energy (ΔΕ∼0.191→0.287eV) and refractive index (n∼2.302→2.357) while absorption edge (λ_c∼456→361A^o) was found to decrease with increase in SrO from 10 to 30mol %.

The critical behavior around the phase transition region is studied for both x = 0.025 and x = 0.05 compositions using various methods such as Modified Arrot plot (MAP), Kouvel-Fisher (KF) plot, and critical isotherm (CI) analysis. The positive slopes of the Arrot plots for both samples revealed that the magnetic phase transition is of second order type based on Banerjee's criterion. The critical exponents β, γ and δ estimated from the magnetic isotherms for x = 0.05 obeys the mean-field model indicating the presence of long-range spin interaction in the system. Meanwhile, the values for x = 0.025 lies within 3D-Heisenberg and Mean Field interaction models which shows the weakening of the long-range interactions and the existence of magnetic inhomogeneity within the system. Furthermore, the variation of effective critical exponents (<em>β</em>_<em>eff</em> and <em>γ</em>_<em>eff</em>) with temperature for x = 0.025 sample is reminiscent of disordered ferromagnetic system.
