| Abstract: | The size controlled zinc oxide nanoparticle is synthesized in the isothermal evaporation method with albumen (egg white). This method is simple and cost effective for synthesis of ZnO nano powder. The egg white foam was assisted to increase the reaction rate and produce the zinc oxide nano powder. This method helps to attain the particle size in the range 13–28 nm. The results from X-ray diffraction patterns and TEM micrograph confirmed the formation of nano crystalline phase with particle size ranges from 13 nm to 28 nm. The samples were further analyzed by using Fourier transform Infrared spectroscopy (FT-IR), photoluminescence spectrum (PL), thermogravimetric analysis (TGA) and Resistivity measurement. The less time consumption in isothermal evaporation process was one of the significant roles for large scale zinc oxide nano powder production. |
