Abstract
Understanding
the growth mechanisms and associated kinetics is a fundamental issue
toward the specific function-oriented controlled synthesis of nanostructures.
In this work, the growth of zinc oxide nanostructures with different
sizes and morphologies are directly observed by in situ liquid-cell
transmission electron microscopy (TEM). Real-time observation and
quantitative analysis reveal that the concentration ratios of the
precursors are responsible for the different growth kinetics, resulting
in different morphology and size of the synthesized ZnO nanostructures
