3.1.2. Scanning electron microscope (SEM) and transmission
electron microscopy (TEM)
SEM measurement which was shown in Figure 2 shows a homogeneous
distribution of the prepared CdO polymorphic, with a median particle
size of 64.58 nm. The TEM measurement showed very well separated
particles with irregular sphere like structure of 45-67 nm. Furthermore,
the measurement showed a rhombic shape-like structure of 50 nm, as shown
in Figure 3. However, the particle size distribution in Figure 3
confirmed that the mean particle size was 55 nm which is in consistence
with XRD and SEM.
