Energy transfer in solid Xe and Kr doped with N2O

Abstract

Photoluminescence excitation, emission, and decay spectra were obtained for solid Xe:N2O and Kr:N2O mixtures using vacuum ultraviolet synchrotron radiation as the excitation source. The principal emitting species were determined to be XeO(1D) and KrO(1S) excimers. Fluorescence decay measurements indicate that the XeO(1D) emission arises from two excited states. Analysis of the emission and excitation spectra leads to the conclusion that XeO(1D) production follows nonradiative energy transfer to N2O from self-trapped excitons in the xenon host.
