Figure 4.

Transmission spectra of ZnO/ZnTe core/shell nanowire arrays. The top inset shows the XRD data, revealing a small shift of the ZnO (002) diffraction peak after being deposited with the ZnTe layer. The bottom inset shows room-temperature photoluminescence spectra of ZnO and ZnO/ZnTe nanowire arrays.
