Abstract
We demonstrate by means of surface-enhanced Raman scattering of 2,6-dimethylphenylisocyanide that the surface potential of Au nanoparticle aggregates changes upon contact with polar organic vapors such as acetone and ammonia by as much as +0.16 and -0.56 V, respectively.
摘要
我们通过 2,6-二甲基苯基异氰化物的表面增强拉曼散射证明，金纳米粒子聚集体的表面电势在与极性有机蒸气（如丙酮和氨）接触时分别发生了高达+0.16 和-0.56 V 的变化。
