Abstract
ZnO nanostructures were developed on a microsphere of ZnS:Cu,Cl phosphor (ZC) for a potential application to a new light source. The growth mechanisms of these nano-structures are very different from those of previously reported methods due to the difference in the zinc ion source of ZnO on the micro-sphere ZC. In this report, ZnO plays two different roles: provision of a seed site and a zinc ion source during the swelling and hydrothermal reaction. In building nanostructures, nano-wires appeared nano-wires first appeared and played a key role in the growth of seed sites of nano-flowers. Additionally, a significant luminance enhancement in the CL spectrum is observed from the emission of the flowers/ZC apparently caused by secondary excitation due to the emission from ZnO nanoflowers.
