| 摘 要： | 采用钠灯作为光诱导反应的光源,利用柠檬酸钠为稳定剂和结构导向剂,以硼氢化钠为还原剂,在水相中光诱导合成三角板银纳米粒子.考察了柠檬酸钠、硼氢化钠比例对粒子形貌的影响,确定最佳比例为[AgNO3]:[Na3C6H5O7]:[NaBH4]=1:25:0.4(物质的量比).采用透射电镜(TEM)、紫外可见吸收光谱(UV-Vis)、X-射线粉末衍射仪(XRD)对实验样品的形貌、光学性质及晶体结构进行表征.

| Abstract: | Triangular silver naoplates were synthesized by irradiating the growth solution,which contained silver cations and citrate anions.The sodium lamp was chosen as the light source.The citrate anions in the system acted as stabilizers,and sodium borohydride acted as reducing agents.The spectral evolution of the growth process was monitored by the UV-vis spectrometer,and the corresponding shape,size and crystallographic structure of nanoparticles in details were investigated by transmission electron microscope(T... |
