摘要
Magnetic nanocrystals have attractedmuch attention in various fields because of their fundamental size and shape dependent magnetism andmany technological applications. In this study, hollow hexagonal alpha- Fe2O3 nanocrystals were synthesized using a normal hydrothermal method. A full growth evolution map of nanocrystals with different shapes was investigated to elucidate the growth mechanism. We had demonstrated the growth mechanism using the selective adsorption and dissolution theory and interestingly found that K+ cations were also a key point during the process of alpha- Fe2O3 nanocrystals growing. At last, the magnetic properties of the hexagonal alpha- Fe2O3 nanocrystals were also investigated.
