Excitonic energy transfer in Au doped and undoped Kr solids

Zusammenfassung

Excitons were produced in Au doped and undoped Kr by VUV irradiation. The dependence of exciton self-trapping as well as trapping (at the Au atoms) on excitation energy and sample temperature has been studied via fluorescence yield spectroscopy. An exciton diffusion model describes the measured spectra quantitatively.
