摘　　要：室温下,以汞灯为光源,硼氢化钠为还原剂,柠檬酸钠为结构导向剂,在200瓦功率下合成了以三角形为主的银纳米颗粒,在600瓦功率下,合成了以十面体为主的银纳米颗粒。用紫外-可见分光光度计和透射电镜对样品的光学性质和形貌进行了表征。此外,还研究了溶液p H值、搅拌对形成银纳米颗粒形貌的影响。At room temperature, using 200 watt mercury lamp as the light source, triangular silver nanoparticles were synthesized by irradiating the growth solution which contained silver cations and citrate anions .The citrate anions in system acted as stabilizers, and sodium borohydride acted as reducing agents. Under the same conditions, using 600 watt mecury lamp as the light source, silver nanodecahedrons were synthesized. The spectral evolution of the growth process was monitored by the UV-vis spectrometer, and the corresponding shape, size of napoparticles in details were investigated by transmission electron microscope（TEM）. We also estimated the influences of stiring and pH value on the final products.
