    <title language="eng">Electronic Polarizability and Optical Basicity of BaO-B2O3-TeO2 Glass System</title>
    <abstract language="eng">[(TeO&lt;sub&gt;2&lt;/sub&gt;)&lt;sub&gt;0.7&lt;/sub&gt;(B&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;3&lt;/sub&gt;)&lt;sub&gt;0.3&lt;/sub&gt;]&lt;sub&gt;1-x &lt;/sub&gt;(BaO)&lt;sub&gt;x&lt;/sub&gt;, x = 0.00, 0.05, 0.10, 0.20, 0.25, 0.30 and 0.35 mol fraction glass series were successfully synthesized by conventional melt quenching method. Amorphous phase of all samples was confirmed through X-ray diffraction while optical properties were determined using UV-VIS spectrophotometer. Fourier Transform Infrared (FTIR) analysis showed that the glass structure consisted of TeO&lt;sub&gt;3&lt;/sub&gt;, TeO&lt;sub&gt;4&lt;/sub&gt;, TeO&lt;sub&gt;6&lt;/sub&gt;, BO&lt;sub&gt;3&lt;/sub&gt; and BO&lt;sub&gt;4&lt;/sub&gt; structural units. The optical band gap energy, E&lt;sub&gt;opt&lt;/sub&gt; which was calculated from Tauc’ plots decreased as the amount of BaO increases, whereas, the Urbach energy value increased. The increase in Urbach energy value was attributed to the increase of defects in glass structure. The refractive indices of glass were found to increase along with the increased amount of BaO, due to the high polarization and high density of host material and glass modifier. The molar polarizability, α&lt;sub&gt;m,&lt;/sub&gt; oxide ion polarizability, α&lt;sub&gt;o&lt;/sub&gt;&lt;sup&gt;2-&lt;/sup&gt; and optical basicity, Λ of the glasses are calculated by Lorentz-Lorenz equation. The glasses were found to possess α&lt;sub&gt;m&lt;/sub&gt; values between 8.106 – 8.489 Å&lt;sup&gt;3&lt;/sup&gt;, and α&lt;sub&gt;o&lt;/sub&gt;&lt;sup&gt;2-&lt;/sup&gt; values between 3.303 to 4.772. Meanwhile, optical basicity increases from 0.115 to 0.893.&lt;/p&gt;</abstract>
