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.
