摘要：

In this letter we report on our interesting finding that the direct mixing of aqueous AgNO3 and NH2OH solutions at room temperature leads to rapid, high-yield production of monodisperse, micrometer scale, highly crystalline, nanotextured Ag dendrites. The surface enhanced Raman scattering (SERS) effect of these Ag dendrites was evaluated by using 4-aminothiophenol (p-ATP) as the Raman probe and the results demonstrate that they exhibit strong SERS effects.
