| Abstract | The effect of ZnS coating over ZnO core is discussed in this present report. Very simple two step wet chemical method was used for the fabrication of this core-shell structure. XRD and HRTEM data reveal the formation of good shell coating over the ZnO core. Photoluminescence spectra shows that emission intensity is at least four times higher when coated with ZnS compare to bare ZnO. Band gap is also calculated using UV-vis spectroscopy. This study will be very useful towards tuning the emission properties and developing intense violet light-emitting and nanophotonic devices. Key words: Core-shell, photoluminescence, violet emission, green emission. |
