Spectroscopic properties, electronic polarizability, and optical basicity of Bi2O3–Li2O–B2O3 glasses

IR analysis of borate glasses containing three alkali oxides

“…The main active vibrational modes of the borate network observed in the present glasses are in three infrared groups (1200-1600 cm −1 , 800-1200 cm −1 , and around 700 cm −1 ) are similar to the values re- ported in the literature 9 . In pure B 2 O 3 glass, the IR band at 806 cm −1 corresponding to characteristic of boroxol ring was not observed in all the present glass samples.…”

Ultrasonic investigations of some bismuth borate glasses doped with Al2O3

“…The increase in density is also consistent with a previous work on the bismuth borate glass system. [16][17][18][19]21 Recent studies 8,[15][16][17][18][19][20][21][22] have shown that progressive addition of Bi 2 O 3 introduces extra-networkformer units. Such units change the crosslink density and the co-ordination numbers of Bi 3+ ions by the creation of Bi-O-B bonds that condense the structure more.…”

“…[4][5][6] Bismuth borate glasses have been extensively investigated due to their transparency in a wide spectral range from UV to IR, which makes them suitable for the fabrication of optical * Author for correspondence (ysaddeek@gmail.com) fibres, detection, sensing and laser technologies (laser host glasses). [7][8][9][10] On the other hand, the research in the field of glasses using ultrasonic parameters such as velocity and attenuation as a function of composition, besides the density and molar volume, has been carried out for many years. [11][12][13] In the study of glass samples, the ultrasonic wave propagation is greatly influenced by the density of the sample.…”

Dielectric Relaxation in CaO–Bi2O3–B2O3 Glasses

“…The above equation (Eq. [7]) is frequently used in the analysis of ac conductivity data. The hopping frequency (o H ) is considered to be a more appropriate parameter for the scaling of the conductivity spectra for the glasses, where dielectric loss peak maxima value cannot be obtained.…”

“…[3][4][5] Recently, considerable attention has been paid to noncentrosymmetric bismuth borate-based compounds keeping their piezoelectric, ferroelectric, pyroelectric, and nonlinear optical properties in view. [6][7][8] Various borate-based single crystals including LiB 3 O 5 , Li 2 B 4 O 7 , BiB 3 O 6 , and BaBiBO 4 have been investigated and reported to posses promising physical properties. [9][10][11][12] We have been making systematic attempts to explore the possibilities of using bismuth borate-based glass systems containing nano/microcrystals of the same composition for pyroelectric, electro-optic, and nonlinear device applications.…”
