Figure 3From: A simple route to vertical array of quasi-1D ZnO nanofilms on FTO surfaces: 1D-crystal growth of nanoseeds under ammonia-assisted hydrolysis process FESEM and cross-section images of ZnO quasi-NRs. Prepared in 10 mM of Zn(CH3COO)2 with different ammonia concentration, namely (A) 36 (standard reaction), (B) 180, (C) 288 and (D) 360 mM. Scale bar is 100 nm.Back to article page
