Abstract

Spectral dip formation at arbitrary wavelengths and the corresponding multicolour changes were achieved by using plasmonic Au nanoparticles on TiO2, based on plasmon-induced charge separation and a coordination effect of iodide ions. The dips were stable in air under white light, in marked contrast to the case of conventional Ag nanoparticles.
