At temperatures of 330°C, 360°C, 390°C, and 420°C, zinc oxide thin films were formed on soda-lime glass substrates using the metalorganic chemical vapour deposition (MOCVD) method using zinc acetate as the precursor. Compressed air was used as the carrier gas, with a flow rate of 2.5 dm3 per minute. The depositions lasted two hours each and were carried out at atmospheric pressure. The thin films were then subjected to FTIR studies to determine their structure and trend with deposition temperatures. The Fourier Transform Infrared (FTIR) spectroscopy technique is a straightforward, non-destructive method for identifying all the elements in a substance. The measurements revealed the presence of lingering organic, oxide, and nitride functional groups, which prominently moderated the material's natural vibrational modes within their respective affiliate wavenumbers, as well as three minor but discernible trends in absorbance peaks, cut-off wavelength, and the presence of the functional groups with temperature. Improved solar cells, triggering sensor devices, p-doped zinc oxide, and other applications are expected to benefit from the materials developed.
