A simple polymer synthesis was used to successfully synthesized Zinc Oxide
Nanoparticles (ZnO NPs), and the influence of the different calcination
temperature on the structural, and optical properties of the material was
observed using several techniques. The formation of ZnO NPs was confirmed by
FT?IR, EDX, XRD, FESEM and TEM images upon calcination from 500?750?C. The
FESEM images showed the ZNO NPs synthesized possessed a hexagonal shape and
tended to become larger at higher calcination temperature. The XRD and FTIR
revealed the precursor to be amorphous at room temperature but transform to a
crystalline structure during the process of calcination. The crystalline and
particle size increase as the temperature was increased. The crystalline size
was between 24?49 nm for all samples calcined at 500?750?C. The optical
properties obtained by UV?vis reflectance spectrometer have further confirmed
the formation of ZnO NPs. The band gap exhibits typical ZnO wide band gap,
and the values decrease with an increase in calcination temperature.
