We present herein silver nanoparticles about 4 nm in diameter coated with a binary mixture of 1‐octanethiol and 2‐(2‐{2‐[(6‐mercaptohexyl)oxy]ethoxy}ethoxy)ethanol. These particles show an affinity towards optically active Eu 3+ ions. The effect of the nanoparticle on the characteristic emission peaks of Eu 3+ is investigated. We use the variation in emission spectra of the ion to establish its binding to the nanoparticles.
