摘　　要：以硝酸银为原料,β-环糊精为还原剂和保护剂,一步法合成了粒径为10~30 nm的单分散银纳米粒子,其结构经UV-Vis,FT-IR,XRD和TEM表征。研究了pH、反应温度和γ[n(1)∶n(AgNO_3)]对反应的影响,并提出了银纳米粒子的形成机制。Silver nanoparticles with diameter between 10 - 30 nm were synthesized by one-pot method using silver nitrate as raw material,β-cyclodextrin as reducing agent and protective agent. The structures were characterized by UV-Vis,FT-IR,XRD and TEM. The effects of p H,reaction temperature and γ[n（1） ∶ n（AgNO3） ]on the reaction were investigated and the mechanism was further discussed.
