| Popis: | The aim of this study was to evaluate the thermal, structural, optical, morphological and anticancer properties of ZnFe2O4 (ZFO) and AlxZn1−xFe2O4 (x = 0.05) (ZAFO) nanoparticles. Zinc ferrite nanoparticles were prepared by chemical co-precipitation method, using polyethylene glycol (PEG) as the capping agent. The synthesized pure and Al-doped ZnFe2O4 nanoparticles were annealed at different temperatures such as 500, 600, 700 and 800 °C. X-ray diffraction analysis was used to determine lattice parameters like X-ray density, oxygen position parameter, distribution of cation among tetrahedral and octahedral sites, ionic radii, and edge lengths of the tetrahedral (A) and octahedral (B) sites and micro strain values. The calculated micro strain values were found to be decreasing with increasing annealing temperatures in both ZnFe2O4 and AlxZn1−xFe2O4 (x = 0.05) samples. The FTIR results confirmed ferrites tetrahedral (~540 cm−1) and octahedral sites (~431 cm−1) metal oxygen vibrations. The morphology of the synthesized ZnFe2O4 and AlxZn1−xFe2O4 (x = 0.05) nanoparticles were studied by field emission scanning electron microscopy (FE-SEM) and particle size was found to be |
