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.
