摘要

Herein, we report the dielectric and nonlinear optical properties of zinc polytitanate (ZPT) nanoparticles with different molar ratios. Zinc polytitanate are synthesized via the sol–gel technique. X-ray diffraction (XRD) indicates that the ZPT exhibits a cubic structure. The computed average crystallite size diminishes from 29 nm, aligning well with the particle size found in High-Resolution Transmission Electron Microscope (HRTEM) investigations. The Energy gap of ZPT is calculated by optical characterization is to be 3.35 eV. Extensive investigations were performed using Fourier Transform Infrared Spectroscopy (FTIR) and photoluminescence assay to expound structural and recombination mechanisms. Photocatalytic analysis explored under visible radiation. The temperature and frequency-dependent dielectric properties of ZPT nanoparticles are utilized to explore the electrical properties. The results reinforce the multifunctional characteristics of the produced ZPT nanoparticles, denoting potential uses in photonics and photocatalytic degradation processes.
