Infrared Spectroscopy Study of Pure Oxides PbO, SnO2 and their Comparison

Abstract

Nanocrystals of semiconducting metal oxides have attracted great interest due to their interesting properties. Therefore, our study came to some physical properties of pure tin oxide and pure lead oxide. Infrared spectral measurements of pure tin and lead oxides showed the presence of vibrational frequencies containing five frequencies for tin oxide and nine vibrational frequencies for lead oxide.The permeability spectra of the SnO2 and PbO compounds were measured, and we calculated each of n, A α , σopt and it was found through the comparison of these amounts for the two compounds that the optical conductivity = 1.214687 (Ωcm)-1, n=9.949 A=2, α=46 cm-1, All previous values are in agreement with the same vibrational frequency of υ = 3450 cm-1 for the lead oxide compound, which is the highest possible.
