3.2 Particle Size Analysis
Particle size analysis was done by dynamic light scattering (DLS) technique as shown
in Fig. 2. The particle size analysis has absolutely confirmed that the synthesized
MgO nanoparticles are in the nano size form. The average particle size of synthesized
MgO nanoparticles is 78.82 nm at intensity of 100%.
3.3 Fourier Transform Infrared (FTIR) Spectroscopy
Analysis of MgO Nanoparticle
The formation of MgO nanoparticles has been confirmed from FTIR spectrum as
shown in Fig. 3. The peak at 580 cm
−1 is assigned to the Mg-O stretching vibration in
Mg(OH) 2 . The absorption peak at 1400 cm
−1 is due to the bending vibration of (OH)
bond. The peak at 878 cm
−1 signifies the out-of-plane aromatic stretching of MgO
