Several bismuth oxide and boron trioxide-containing alkali Earth oxide glasses were examined. The glass 10XO-40Bi 2 O 3 -49B 2 O 3 -1CuO [XBBC] is prepared and characterized using Mg, Ca, Sr, and Ba as X. XRD tests showed that [XBBC] glasses were amorphous after melt quenching. Molar volume, density, and other physical properties were meticulously examined. Density follows glass composition: BBBC > SBBC > MBBC > CBBC. The crystal density of each alkaline Earth oxide affects density. The maximum density was 6.695 g cm −3 for [BBBC] glass and the lowest was 6.29909 g cm −3 for [CBBC] glass. Optical studies estimate Urbach energy from 0.298 eV [CBBC] to 0.952 eV [BBBC] and optical band gap energy from 2.785 eV [MBBC] to 2.890 eV [BBBC]. Urbach energy is lowest in [CBBC] glass and greatest in [BBBC]. Optical energy gap is lower for [MBBC] than [BBBC] glass. Glass samples showed non-bridging oxygens in the glass structures. FTIR spectra showed Bi 2 O 3 stretching vibration. The wavenumber of BO 3 and BO 4 vibrations was suitable. BiO 6 units were found in FTIR. The FTIR and Raman spectra show that the glass is comprised of BO 3 and BO 4 units with distinct borate groups.
