Facile Synthesis of Monodisperse ZnO Nanocrystals by Direct Liquid Phase Precipitation
Figure 3
TEM images of the OLA-ZnO NCs obtained under different in situ ageing conditions: (a) 60°C for 48 hours; (b) 60°C for 188 hours; (c) 80°C for 48 hours; (d) 105°C for 48 hours and (e) the maximum mode of the nanocrystal size distribution from image (a)–(d); and (f) a sequential addition of metal cations where the reaction is initiated and run for two hours and additional stoichiometric amounts of and solids are added during the extended ageing treatment ( 60°C for 188 hours). All scale bars are 50 nm.
