Analytical Study of Infrared Spectrum for SnO2:Sb(4wt%) Compound
Abstract
The nanocrystals of semi-conductive metal oxides attracted great attention because of their interesting properties. Therefore, our study of some physical properties of the pure and Sb doping Tin Oxide compound. The measurement of the infrared spectrum of pure tin oxide compound shows vibrational frequencies which has two energy (415.585, 574.683) cm-1 and the Sb doping Tin Oxide with a rate of (4wt%) shows vibration frequencies and the most prominent is which has two energy (417.513, 669.178) cm-1. the study showed that the largest value of the absorbance, absorption coefficient was in the sample Sb doping Tin Oxide compound respectively are A=0.7560, α=17.389 cm-1, at the vibrational frequency 3447.13 cm-1, and the refractive index for pure tin oxide ranged from (1.832 - 2.371). As for the Sb doping Tin Oxide compound, the refractive index value was between (1.709-2.643).
