Energy transfer and highly resolved emission of [Ru1-xOsx(bpy)₃](PF₆)₂

Abstract

The emission properties the title compound are investigated at T = 2 K and high magnetic fields. The radiationless energy transfer from the [Ru]-host to the [Os]-guest is governed by a fast process and a slow one, which indicates a relatively ineffective transfer in the host material. Moreover, the guest emission is found to be highly resolved and is assigned to result from a superposition of vibronic components emitted from three different sites.
