摘要
In this paper, thermal treatment of Zn(NH3)(4)(2+) precursor in ethanol solvent leading to the formation of the ZnO hollow spheres is reported. It was demonstrated that the pH value of the initial mixture and the volume ratio of the ethanol with the solution plays the key function in the formation of hollow spheres. Transmission electron microscopy and scanning electron microscopy images showed that hollow spheres of similar to 600 nm in diameter were built by ZnO nanorods. On the basis of experimental results, a possible formation mechanism in the growth processes is discussed.
