| Abstract: | ZnO nanoparticles of uniform size have been synthesized at 200 °C and 300 °C by using [Zn(INA)2(H2O)4], where INA is the isonicotinate anion, as a metal-organic precursor. The synthesized oxide materials have been investigated by various physical techniques such as powder XRD, TEM, FE-SEM and UV-vis spectroscopy. The spherical particles obtained at 300 °C are somewhat larger in size. The optical band gap of ZnO shrinks from 2.54 to 2.40 eV as the formation temperature is increased from 200 to 300 °C. It is found that irrespective of the excitation wavelength, the ZnO sample obtained at 200 °C exhibits stronger luminescence at 395 nm. |
