Abstract :

ZnOnanoparticles (NPs) have been synthesized using gelatin as surface modifyingagent by co–precipitation method. Linear optical investigations have been performed using ultraviolet–visible (UV–vis) spectroscopy and fourier transform infra–red (FT–IR) spectroscopy. Strong blue–shift of maximum absorption wavelength in the UV–vis spectra clearly attests the formation of ZnO NPs. Maximum blue–shift has been observed for the sample prepared using highest concentration of gelatin. FT–IR spectrum shows rotational–viational peaks corresponding to ZnO and gelatin which clearly indicates the attachment of gelation on the surface of ZnO. Particles sizes of all uncalcined and calcined NPs have been calculated using Effective Mass Approximation (EMA) method. X–ray diffraction (XRD) pattern confirms the formation of pure phase wurtzite structure of ZnO and particle size was calculated using DebyeScherrer formula and agrees with UV–vis data. Field emission scanning electron microscopy and transmission electron microscopy reveals the uniform surface morphology of ZnO NPs.
