摘要：
High-quality ZnO nanocombs were synthesized on Si substrates coated with Au films by evaporating ZnO powders with a high yield. The morphology of the ZnO nanocombs was characterized by scanning electronic microscopy. In order to study the dynamic process of near-band edge emission, the temperature-dependent photoluminescence spectra were measured. The first excited state emission of A-free exciton centered at 3.403 eV was observed at 87 K.
