Abstract:The recent advances of methods of controlling the crystal phases, crystal facets, shapes and sizes were reviewed. The effects of surfactants, solvents and doping ions on the morphology and crystal phase of metal oxide semiconductor nanocrystals in the liquid-phase synthesis processes were introduced in detail. The characteristics of different methods were also summarized. Developing the green, high-selectivity processes to prepare monodispersed metal oxide nanocrystals with special structures is still the research trend.
Key words: metal oxide semiconductor; nanocrystals; liquid-phase synthesis; morphology; crystal phase
