Introduction Unique physical and chemical behavior of room temperature ionic liquids (RTILs) has made them very popular among research fraternity, as they are no longer being employed merely as ‘Green Solvents’ in organic chemistry rather find enormous applications in diverse fields including nanomaterial technologies, electrochemical applications , biocatalytic transformations, colloid and interface science and separation processes etc [1-3].
RTILs with longer alkyl chains are generally found to be surface active because of their inherent amphiphilicity and tendency to form aggregated structures.

Diffraction patterns of two samples are corresponding to typical ZnO (002), (100) and (101) planes, indicating six wurtzite structure and good crystallization, basically the same diffraction peak shape, but its width decreased with the increasing heat treatment temperature , strength slightly increased, which showed that with the increase of heat treatment temperature, grain growth.

Abstract.
PL spectra of the as-prepared ZnO structures were measured with light exaction at 325 nm at room temperature as illustrated in Fig. 1(c), which exhibited one green emission around 500 nm.

The monodisperse spherical particles used as raw materials to prepare photonic crystal materials and multifunctional catalysts with core-shell structure have attracted wide attention and become the research hotspot in chemistry, materials science, and many other disciplines and cross-cutting areas [5].
Accordingly, silica spherical particles have been prepared by utilizing various synthetic approaches including those based on emulsion chemistry and using morphology template [6,7].
