摘要：
Patterned ZnO nanodot ( ND) arrays and a ND-cavity microstructure were realized on an anodic alumina membrane ( AAM) surface through a spin-coating sol -gel process, which benefits from the morphology and localized negative charge surface of AAM as well as the optimized sol concentration. The growth mechanism is believed to be a self-assembly process. This provides a simple approach to fabricate semiconductor quantum dot ( QD) arrays and a QD-cavity system with its advantage in low cost and mass production. Strong ultra-violet emission, a multi-phonon process, and its special structure-related properties were observed in the patterned ZnO ND arrays.
