Abstract


The nanocrystals of semiconducting metal oxides have attracted great attention because of their interesting properties. Therefore, our study of some physical properties of the pure and  Sb doping Tin Oxide powder , The measurement of the infrared spectrum of pure tin oxide powder shows vibrational frequencies (415.585 - 574.683 - 1641.13 – 2125.3- 3432.67) cm-1 and for Sb doping tin oxide ;(x=0.03) shows vibration frequencies and the most prominent is ( 573.719 – 941.092 – 1384.64 – 1637.27 – 3415.56  ) cm-1 , the study showed that the greatest value of the absorbance and absorption coefficient was in doping sample respectively  A = 0.819, α = 18.839 cm-1 corresponding to the wavenumber ʋ = 573.719 cm-1, the greatest value of the optical conductivity was in pure sample 0.0831(Ωcm)-1 corresponding to the wavenumber ʋ = 3432.67 cm-1  and the refractive index for pure tin oxide ranged from [1.832 - 2.371]. As for the Sb doping Tin Oxide powder, the refractive index value was between [1.122 – 2.152 ].

Keywords: Tin Oxide - infrared spectrum - absorbance - absorption coefficient - refractive index - optical conductivity.
