This study reports on a new method for manipulating the size and shape of silver nanostructures using supercritical carbon dioxide (CO 2 ) in the presence of polyvinyl pyrrolidone (PVP) and ethylene glycol (EG). The temperature and pressure of CO 2 as well as the ratio of the capping agent PVP to the precursor of silver nitrate are used to control the growth of the silver nuclei and...
