Figure 6From: A simple route to vertical array of quasi-1D ZnO nanofilms on FTO surfaces: 1D-crystal growth of nanoseeds under ammonia-assisted hydrolysis process Typical UV-VIS optical absorption spectrum of ZnO quasi-NRs. Two separate excitonic characters, namely A- and B-excitons, were observed in the spectrum, reflecting the ZnO quasi-NRs are high-crystallinity in nature.Back to article page
