VUV-UV-vis photoluminescence, X-ray radioluminescence and energy transfer dynamics of Ce and Eu in SrMgSiO.

Ce and Eu doped and Ce-Eu co-doped SrMgSiO phosphors are prepared a high-temperature solid-state reaction technique. The synchrotron radiation vacuum ultraviolet-ultraviolet (VUV-UV) excitation and ultraviolet-visible (UV-vis) emission spectra of diluted Ce and Eu doped SrMgSiO samples are measured at cryogenic temperatures. The electron-vibrational interaction (EVI) between Ce and its surroundings is analyzed.
