Characterization of PbO-B2O3-GeO2-La2O3 and PbO-B2O3-SiO2-ZnO glasses: refractive, acoustic, photo-elastic and acousto-optic properties

Abstract

New high-lead glasses with two different compositions are subjected to comprehensive material characterization. In particular, their refractive indices, optical transmission spectra, photo-elastic, piezo-optic and strain-optic constants, ultrasound velocities and elastic constants are measured. We find the shortwavelength absorption edges as λ edge = 383 and 475 nm for these compounds. The acousto-optic figures of merit are calculated for the glasses under study. Their maximal acousto-optic figures of merit turn out to be higher than the corresponding values for fused silica and dense flint glasses, which are known as vitreous materials widely used in serial acousto-optic modulators.

Investigation of the acousto‐optical properties of Ge–As–Te–(Se) chalcogenide glasses at 10.6 μm wavelength

“…The measured results of elastic modulus using ρ of glasses are in accordance with the appropriate relations in Ref. [31]. In the first series of glass system Ge 10 As 90−x Te x , ρ increased from 5.212 to 5.523 g/cm 3 with increased Te content from 30 to 70 mol% as shown in Table 3, whereas E decreased from 20.93 to 19.15 GPa, G decreased from 8.288 to 7.509 GPa and υ increased from 0.263 to 0.275, respectively.…”

Structural, Optical, and Magnetic Studies of the Metallic Lead Effect on MnO2-Pb-PbO2 Vitroceramics

“…The second region of UV-Vis bands located between 300 and 500 nm is due to the presence of Pb +2 (320 nm), Mn +2 (420 nm) [13,14], and Mn +3 (490 nm) ions [15] in the structure of glass ceramics. The band situated at about 420 nm is attributed to the transition of 6 A 1 (S) to 4 A 1 of Mn +2 ions [16].…”

“…Lead-containing glass and vitroceramics can be produced viathe melt-quenching method at a low temperature [1][2][3]. Nowadays, lead glass and vitroceramicscontainingdifferent transition metal ions can be used in optoelectronics andacousto-optics for the production of devices and electrodes in batteries [4][5][6][7][8].…”
