The influence of Cu2+ ions on the ionic, electronic conductivity and optical characteristics of Li2O-SrO-B2O3 system
Source abstract
Abstract
Melt quenching technique was used for preparing the glass network 10Li 2O-30SrO-(60-x)B 2O 3: xCuO (0 < x < 1, where x = 0, 0.2, 0.4, 0.6, 0.8, and 1 mol%). The samples were investigated by analysing spectroscopic and dielectric properties. X-ray diffraction (XRD) asserted the glassy nature of the samples. Optical absorption spectra of the specimens displayed a prime band centred nearly at 750 nm due to Cu 2+ ions. A continuous increase in the intensity of this band is noticed with a rise in the concentration of CuO. Electron spin resonance (ESR) spectra of the glasses confirmed the existence of Cu 2+ ions. Spin-Hamiltonian parameters of the specimens were estimated. An analysis on the Fourier transform infrared (FTIR) curves confirmed the bands due to conventional borate units. The dielectric investigations supported the depolymerization of the specimens with an increase in the content of CuO.
