Abstract :
In this work, zinc oxide and titanium dioxide
nanoparticles were synthesized using the sol-gel method.
UV-visible spectroscopy, scanning electron microscopy
(SEM), and X-ray diffraction (XRD) were used to
calculate the particle size of the synthesized samples.
The ZnO had a primitive hexagonal structure with an
average particle size of 86.72 nm, according to the XRD
data, whereas the TiO2 crystal structure was body-
centered tetragonal with an average particle size of
94.72 nm. The average particle sizes for ZnO and TiO2
were 85.49 nm and 89.61 nm, respectively, derived from
SEM images using the histogram approach. The optical
results demonstrate the absorbance ratio (A spr /A
absorbance) at 300 nm for ZnO and 275 nm for TiO2 in
dependence of the absorbance for ZnO and TiO2
nanoparticles at the surface plasma resonance peak.
The particle sizes were 88.4nm and 97.3 nm for ZnO
and TiO2 respectively. The three methods that were
used to determined particle size gave close values.
