摘要	We reported on the dramatic chemical reshaping of silver nanoparticles upon exposure to cetylrimethylammonium bromide(CTAB) in aqueous solutions. In the presence of concentrated CTAB, the triangular silver nanoplates were observed to undergo a morphological change from truncated triangular, elliptic nanoplates to circular nanoplates. When dilute CTAB was employed, the triangular silver nanoplates were transformed into spindle silver nanoplates. Such transfigurations of silver nanoparticles were related to the concentration of bromide ions and organic groups of CTAB in the solutions. By changing the shape of silver nanopartilces their corresponding optical properties were tuned accordingly.
