Abstract
The novel Ni-doped magnesium oxide nanoparticles were synthesized using the co-precipitation technique and
optimized across various dopant concentrations and annealing conditions. Unlike previous studies, this work
systematically investigates the influence of Ni concentration and thermal treatment on thermoluminescence (TL)
properties of the synthesized MgO: Ni nanoparticles. The crystalline properties, morphology, composition, and
structure of the fabricated samples were characterized. XRD analysis revealed a pure cubic MgO phase with
crystallite sizes below 50 nm. After 20 Gy gamma irradiation, the sample doped with 1 mol% Ni and annealed at
700
C exhibited the highest integrated TL signal. The material showed a linear gamma dose response up to 1000
Gy and excellent signal stability over 30 days. Kinetic parameters were determined using curve fitting based on a
general-order kinetic model. These findings highlight the potential of MgO: Ni nanoparticles as efficient phos
phor for high dose dosimetry.
