Two-dimensional (2D) hierarchical tin dioxide (SnO2) flower-like architectures consisting of sheet-like nanoparticles have been successfully prepared by a simply mild hydrothermal method based on the reaction between tin foil, NaOH and KBrO3. The photoluminescence (PL) spectrum exhibit that the flower-like architectures of SnO2 have strong PL emission, which suggest its possible applications in nanoscaled optoelectronic devices. The formation process of SnO2 architectures is investigated and the corresponding mechanism is also proposed.
