To address this gap, ZnGa?O? nanoparticles were synthesised using a hydrothermal method at different pH levels, with X-ray diffraction (XRD) confirming a phase-pure cubic spinel structure at pH = 10. Rietveld refinement further validated the crystal structure and was visualised using VESTA software. FTIR confirmed the presence of characteristic metaloxygen bonds. FESEM revealed an agglomerated nanoparticle morphology. TEM verified the particle structure, and EDAX confirmed elemental composition, collectively supporting the cubic structure. XPS validated the oxidation states of Zn? and Ga ?. Optical characterisation using photoluminescence and diffuse reflectance spectroscopy confirmed the wide bandgap nature of the material. Strong blue emission under UV excitation demonstrated the photoluminescent behaviour. DC conductivity measurements were conducted to evaluate the electrical transport behaviour of the synthesised material. The third-order nonlinear optical (NLO) properties were systematically investigated using open- and closed-aperture Z-scan techniques under continuous-wave and nanosecond pulsed laser excitation. The material exhibited reverse saturable absorption, a negative nonlinear refractive index, and a large third-order susceptibility, along with efficient optical limiting behaviour under pulsed excitation. These results demonstrate that hydrothermally synthesised ZnGa?O? nanoparticles possess strong third-order nonlinearity and effective optical limiting performance, establishing zinc gallate as a promising spinel oxide for laser protection and advanced photonic applications. 2026 Elsevier B.V.
