Putting the AgCl nanoparticle as crystal nucleus and in the condition of the existence of tri-sodium citrate, the Ag+, which covers the surface of AgCl nanoparticle, photochemically reduces to Ag and thus Ag/AgCl composite nanoparticle is obtained. The spectroscopic characters of Ag/AgCl nanoparticle in aqueous solution have been studied. There are two resonance scattering peaks at 310 and 590 nm, and an absorption peak at 400 nm.
以氯化银纳米颗粒为晶核，在柠檬酸钠存在的条件下，覆盖在氯化银纳米颗粒表面的银离子通过光化学还原为银，从而得到银/氯化银复合纳米颗粒。研究了银/氯化银纳米颗粒在水溶液中的光谱特性。在310和590nm处有两个共振散射峰，在400nm处有一个吸收峰。
