Investigation of the effect of Au2O3 dopant on elastic properties of PbO-B2O3-SeO2: Er2O3 glass ceramics by ultrasonic techniques

Influence of Gold Nano Particles on Dielectric Features A.C. Conductivity and Dielectric Breakdown Strength of PbO-B2O3-SeO2:Ho2O3 Glass Ceramics

“…Other details of measutrements that include characterization techniques, optical absorption (OA), IR, Raman, PL spectra and decay profiles were reported earlier. 19,21 As mentioned in the introduction part, in this study the concentration of free volume defects in the material were estimated using PAS spectroscopy, with 22 Na isotope (100 kBq) as positron source. The spectra were recorded using "Ortec" PAS system.…”

Such investigations additionally pointed out that as Au 2 O 3 content was raised there was a hike in the concentration of [SeO 3 ] 2− groups and Au 0 MPs in the glass ceramic and caused to enhance the internal disorder of the host glass.…”

Copper doped strontium Indium-borate glasses: FTIR, Raman, EPR, optical and structural studies

“…The density at room temperature was determined by the Archimedes method with xylene as immersion liquid. The statistical error in the density was ±0.025cm 3 . Three distinct pieces of glass were chosen from each batch for density measurements, and the average value was reported for each sample.…”

“…Recently glasses have become the center of attraction for manufacturing radiation shielding materials, optical and other technical devices etc. [1][2][3]. The main objective of the source materials used to prepare glass should be easy to melt, economic, ecofriendly, good transparency at ambient temperature, mechanical strength, physical isotropy, no grain boundaries, exceptional insulating properties, etc., [4,5].…”
