摘要

We report the first synthesis and characterization of Manganese zirconium Phosphate (MZP) (MnZr(PO4)2), a novel material prepared using solid state reaction methods. The crystal structure of MZP is equivalent to the structure of SrZr(PO4)2 with space group -P1, was confirmed by X-ray powder diffraction, the calculated crystallite size was about 54 nm. Band gap determined using Wood-Tauc was about 4.5 eV. FTIR spectroscopy, exhibits vibrations corresponding to the Zr–O group and PO4 octahedron. Additionally, we investigated the Thermoluminescence characteristics of MZP when subjected to γ γ-ray radiation at various doses. Thermoluminescence (TL) glow curves were recorded at a constant heating rate, and the associated trapping parameters—including order of kinetics, frequency factors, and activation energies—were meticulously calculated. The broad TL glow curve of MZP indicates potential use as a dosimetric material for measuring γ-ray radiation exposure. Our findings highlight the potential of MZP in applications requiring precise radiation measurement, contributing to the development of advanced materials in radiation dosimetry.
