Stepwise Growth of Hollow Hexagonal α-Fe2O3 Nanocrystals

Stepwise Growth of Hollow Hexagonal α-Fe2O3 Nanocrystals

Magnetic nanocrystals have attracted much attention in various fields because of their fundamental size and shape dependent magnetism and many technological applications. In this study, hollow hexagonal α-Fe2O3 nanocrystals were synthesized using a normal hydrothermal method. A full growth evolution...
