Vibrational Spectroscopy of ZnO-ZnS Nanoparticles
G. Janita Christobel
Abstract: A Fourier Transform Infrared spectrum represents the nger-print of a sample with absorption peaks which correspond to the frequencies of vibrations between the bonds of the atoms making up the material. This paper reports the FT-IR spectroscopy of ZnO-ZnS nanoparticles synthesised via a simple solvothermal method. Five samples of ZnSxO (1-x) nanoparticles with x = 0.0, 0.25, 0.5, 0.75 and 1.0 have been synthesized. The FTIR spectrum was recorded on a Shimadzu FTIR-8400S, Prestige-21 spectrophotometer in a KBr matrix. The finger print region peaks observed around 550and 650 cm-1 explain the distinct vibration of zinc oxide and the same around 570 - 680 cm-1 show the stretching vibration of zinc suphide. The FT-IR spectra of other three mixed samples show a mixture of peaks both corresponding to ZnO and ZnS. This result gives a way for us to confirm that the synthesised ZnO-ZnS nanoparticles form hetro-structured zinc oxide and zinc sulphide. Peaks observed around 3500 cm-1 is assigned to O-H vibration and that around 1500 -1650 cm-1 and at 2370 cm-1 are due to C=O stretching mode, arising from the absorption of atmospheric water and CO2 on the surface of the nanoparticles respectively.
