AI Article Synopsis
- - The study investigates how aryl iodides, when attached to gold nanoparticles, show increased luminescence properties.
- - When these compounds are chemisorbed onto poly(-vinylpyrrolidone)-protected gold nanoparticles, the luminescence is greatly enhanced compared to when they're not attached.
- - Kinetic analysis indicates that the enhanced luminescence results from excimer formation, which occurs more quickly than the typical process of intersystem crossing involving heavy atoms.
Article Abstract
The photoluminescence properties of aryl iodides chemisorbed on gold nanoparticles were examined. Chemisorption of a series of aryl iodides onto poly(-vinylpyrrolidone)-protected Au nanoparticles (Au:PVP) in solution resulted in highly enhanced luminescence. Kinetic studies revealed that the photoluminescence is derived from the excimer formation of aryl iodides on Au:PVP, and the process is significantly faster than intersystem crossing by the heavy atom.
