dc.description.abstractAnnealing is a process that often results in aggregation of the crystallite particles and therefore an increase in crystallite size is often observed. In this study, the behavior of biopolymer-assisted synthesized cerium oxide nanoparticles under the influence of annealing is investigated. Cerium (III) alginate hydrogels were thermally decomposed at 450 °C to synthesize cerium oxide nanoparticles, which is reported in literature as a green method and results in surface functionality of the nanoparticles. The particles were annealed at two different temperatures (600 and 800 °C) for 2, 4 and 8 hours. X-ray diffraction was used to characterize the powder samples for observing the average crystallite sizes, which were calculated using Scherrer’s equation. Additionally, the grain size distribution of the nanoparticles is also studied by a semi-numerical method based on diffraction patterns. Results indicate that the annealing increases the sample size 2 to 4 times, which can be useful for designing the average crystallite size in advanced studies such as optics and drug delivery.en_US
