The reflectivity spectra of semiconducting Bi4Sr3Ca3Cu2O10 glasses were measured over the frequency range between 100 and 4000 cm−1, and were analysed using Kramer-Kronig routines. It is observed that the static and high frequency dielectric constant varies as the bismuth is partially replaced by silver and nickel. The X-ray diffraction and the dc resisitivity measurements shows a semiconductin...

Objectives: To investigate the effect of B2O3 replaced by Nd2O3 studies on spectroscopic characteristics trivalent neodymium (Nd3+)-doped glasses using XRD, FTIR, absorption, and emission spectroscopy. Methods: The were synthesized conventional melt quenching technique at 11500 C. amorphous nature samples was confirmed x-ray diffraction studies. Findings: addition concentration affects absorpti...

The annealing effect of an alkali borate type glass below its softening point was investigated according to the Na2O-B2O3 binary system. samples were doped by introducing different amounts copper oxide (CuO). properties elaborate glasses before and after studied. X-ray diffraction (XRD) as well optical infrared spectroscopy used in this study. results obtained show that annealing, is, a heat tr...
