“…These absorption spectra reveal a broad band having its maximum intensity at 350 nm for the three cited samples. This absorption band of PO4 3− is caused by a charge transfer from the oxygen legends (O 2− ) to the central phosphor atom (P 5+ ) [9].This result is hopeful because these materials possess an excitation wavelength in the UV region. The P 5+ ion has a closed-shell electronic structure.…”

New Zn2P2O7, K2ZnP2O7 and KZn1.5P2O7 compounds were synthesized with conventional solid solid reaction method. The optical properties have been studied by using UV-Visible spectrophotometer. The optical band gaps (Eg) were found to be 3.76 eV, 3.39 eV and 3.59eV respectively. Optical parameters such as refractive index, Cauchy's parameters and conductivity were deduced. The refractive index fitting in the visible range and the dispersion parameters (E0 and Ed) of these compounds were estimated using the Wemple-DiDomenico model.

“…Research on materials used as anode confirms that LiZnVO4 with specific nanoscale sizes can be used in the lithium-ion secondary battery as the negative electrode (Wang et al 2018). The properties of LiZnVO4 due to its use in lithium storage as it has a high capacity extended by overcharging with high stability in charge and discharge cycles improving the interpretation of secondary Li-ion batteries according to their short diffusion paths and high surface areas (Grandhe et al 2012;Ram 2011;Wang et al 2018).…”

This work aims to prepare LiZnVO4 nanoparticles and incorporate them into PVDF as a host polymeric material using the casting method for rechargeable Li-battery applications. The effect of LiZnVO4 on the structural and optical properties of the samples was studied using XRD, FT-IR, and UV-is techniques. Moreover, the electrical conductivity of the prepared films was studied. The XRD spectra show the semicrystalline structure of PVDF and the rhombohedral structure of LiZnVO4. Scherer's equation was used to determine the crystallite size of LiZnVO4 which is nearly 83 nm. The interaction between PVDF and LiZnVO4 was approved by shifting some FT-IR bands. The band gap energies were decreased by increasing LiZnVO4 due to the density in the localized states in the mobility band gap in PVDF. The AC parameters as a function of frequency and temperature were investigated in detail. Both ε' and ε" had their maximum values at low frequencies and decreased as the frequency and temperature increased. The XRD and FT-IR findings corroborate the increased dielectric characteristics and tan δ at 5 wt. percent LiZnVO4, suggesting their potential use as a basic material in the development of cutting-edge energy storage devices and lithium-ion batteries.

The dielectric properties and tan δ were improved, particularly 5 wt% of LiZnVO4, which confirms the XRD and FT-IR results indicating their suitability as a suitable base material for designing and developing promising energy storage devices and lithium batteries.
