From: Intensify the application of ZnO-based nanodevices in humid environment: O2/H2 plasma suppressed the spontaneous reaction of amorphous ZnO nanowires

Figure 1

The spontaneous reaction of ZnO nanobranches (NBs) can be observed by optical microscope (OM). The morphology of ZnO NBs is varied with time and humidity (70% ± 2.5%, 80% ± 2.5%, and 90% ± 2.5%). (a, b, c) In high humidity (90% ± 2.5%), plenty of ZnO particles can be found around the ZnO NWs about 12 h. (d, e, f) When the humidity is around 80% ± 2.5%, a few ZnO NBs can be found within 12 h. (g, h, i) In low humidity (70% ± 2.5%), there are no ZnO NBs can be formed until 240 h.
