Effect of high pressure on the emission spectrum of [Ru(bpy)₃](PF₆)₂ single crystals

Abstract

Investigations of the emission of [Ru(bpy)₃](PF₆)₂ single crystals under high pressure are reported for the first time. The spectra are recorded at room temperature up to 52 kbar. The following pressure effects are observed: a very small red shift, a distinct sharpening of emission spectra, and a considerable decrease in emission intensity. Model conceptions are presented to account for the experimental results.
