nanostructures such as nanopores, [1] nanowires, [2]nanobelts [3], and nanorods [4] have attracted great interestdue to their unique electrical and photonic properties forpotential applications in chemical sensors, optoelectronics,and field-effect transistors. Thanks to the high surface-volume ratio,[r]

emission was significantly enhanced afte r the deposition of Al2O3and ZnO shells, which are attributed to thedecrease in oxygen interstitials at the surface and the reduction in surface band bending of ZnO core, respectively.The shift of deep-level emissions from the ZnO/ZnO core-shell NRAs was obse[r]
