Abstract

In the present communication, BaO/ZrO2/PbO (BZPO) nanocomposites (NCs) are synthesized using the solution combustion method using Aloevera gel extract as a reducing agent, followed by calcination at 600 °C for 3 h. The obtained nanoparticles undergo various analytical characterization techniques, including powder X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy, and ultraviolet–visible spectroscopy. The Bragg reflections confirm the formation of BZPO NCs. BaO and ZrO2 crystallize in the tetragonal phase, whereas PbO crystallizes in β phase orthorhombic system. The surface morphology consists of a large number of thin nanoflakes. The appearance of nanoflakes indicates the increase in surface area. The energy band gap was tuned to 3eV. The gamma radiation shielding properties using an NaI(Tl) detector connected to an MCA are evaluated. The shielding parameters, such as mass attenuation coefficients, HVL, TVL, and mean free path, are found to be 0.143, 0.088, 0.058 and 0.054 cm2/g, 6.025, 9.792, 14.85 and cm, 15.95, 20.02, 32.54 and 49.37 cm, 53.03, 8.695, 14.13, 21.43 and 23.02 cm at energies 511, 662, 1173 and 1332 keV respectively. Thus the procured NCs exhibit good shielding.
