Titanium induced structural modifications in bismuth silicate glasses

Manganese modified structural and optical properties of bismuth silicate glasses

“…The decrease in density with increase in MnO 2 content is expected in the present system as heavier Bi 2 O 3 is being replaced by the lighter MnO 2 . The same type of behaviour has also been reported by several other researchers for glass compositions [8,12,13]. The molar volume (V m ) of samples was calculated using the following relation [14] …”

“…Therefore, deconvolution of the experimental data of FTIR and Raman spectra was necessary and was performed using the inbuilt ''multiple peaks fit'' module of Origin Pro 8.6 software. The procedure for deconvolution of the spectra used has already been published elsewhere [8]. The statistical validation of fitting was tested by applying F-test [11].…”

“…The density is one of the tools to reveal the degree of structural changes of the glass network with composition [8]. The values of density (q) measured for all the samples using Archimedes's principle are given in Table 1.…”

“…possibilities to extend the properties of these glasses by modifying their structure. The structural and electronic transport properties of Ti based bismuth silicate glasses have been reported recently [8][9][10] but there is hardly any report on the structural characterization of MnO 2 -Bi 2 O 3 -SiO 2 glass system. Therefore, it is desired to carry out the detailed study of the effect of manganese on the physical, optical and structural properties of bismuth silicate glasses.…”

“…The deconvolution of FTIR and Raman spectra was performed using "Multiple Peaks Fit" module of Origin Pro 8.6 software by using Gaussian shape function. The procedure for deconvolution of the spectra has already been published [21]. The statistical validation has also been tested by applying F-test [22].…”
