Abstract
Ag(0) and Au(0) nanoparticles suspended in dilute aqueous solutions containing (CH(3))(2)SO are photochemically unstable. The light source of a diode-array spectrophotometer induces, within less than a minute, particle growth and aggregation. The results indicate that this process is triggered by UV light absorption by the (CH(3))(2)SO.
摘要
在含有 (CH(3))(2)SO 的稀水溶液中悬浮的 Ag(0) 和 Au(0) 纳米粒子在光照下不稳定。二极管阵列分光光度计的光源在不到一分钟的时间内诱导了颗粒的生长和聚集。结果表明，这个过程是由 (CH(3))(2)SO 对紫外光的吸收引发的。
