“…All prepared samples exhibit broad peaks at around 25° and 45degree. These broad peaks in the XRD patterns are indicative of short-range order, further confirming the amorphous or glassy nature of the prepared samples [5][6][7][8][9]. The optical absorption spectra of the synthesized CRBBN glasses were analyzed by a UV770 V-770 spectrophotometer.…”

“…Incorporating chromium oxide (Cr 2 O 3 ) can tailor the glass for applications in lasers and high-temperature environments. This study explores the addition of Na 2 O and Chromium to bismuth borate glasses, examining their transformation into crystalline structures and investigating physical, mechanical, and optical properties using UV analysis [7][8][9][10][11]. The research aims to comprehensively understand the structural implications of chromium ions in multi component bismuth borate glasses, synthesizing glasses with varying amounts of Cr 2 O 3 and analyzing their properties.…”

The glasses, composed of multiple components, contain chromium oxide x.Cr 2 O 3 .(70-x)B 2 O 3 .18Bi 2 O 3 .12Na 2 O, where x varies (x=0, x=0.15, x=0.25, x=0.35, x=0.50 mol %), synthesized using the melt-quench method. The amorphous nature of the synthesized samples was confirmed using X-ray diffraction (XRD). We observed that an increase in Cr 2 O 3 content resulted in a rise in the density (ρ) of the glasses, ranging from 3.88 g/cm 3 to 4.009 g/cm 3 . The molar volume displays behavior opposite to the density and oxygen packing density (OPD) trends exhibited augmentation with elevated chromium oxide concentration. Optical absorption spectra have been recorded within the frequency range of 200 to 3200 nm. The UV-VIS absorption spectra of polished glass samples with parallel surfaces revealed a reduction in the optical band gap (E g ) as the Chromium content increased. These findings provide a foundational basis for customizing glass compositions to meet specific technological requirements, encompassing applications in optics and radiation shielding. Recorded spectra are analysed to evaluate refractive index (n), optical band gap (E g ) and Tauc's plots, Urbach energy (E u ).
