Özet
Annealing 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.
