Objectif The unique properties of synchrotron radiation applied to the study of luminescence and the fundamental optical properties of materials will enable a deeper understanding of known phenomena to be obtained and new ones to be observed.The conversion of relatively high-energy radiation into low-energy (UV/visible) luminescence is a phenomenon widely applied in practice in X-ray screens, scintillators, X-ray image plates, etc. However, the fundamental mechanisms associated with different stages of this process have not been studied in any detail and are only poorly understood. The internal relaxation processes following high-energy excitation involve a multiplicity of electronic excitations, defect creation, energy transfer between emission and quenching centres, and interaction with the surface states. Only by using synchrotron radiation is it possible to undertake the range of measurements starting with the VUV through the XUV to the X-ray region so as to help understand the contribution of these phenomena separately. The temporal structure of synchrotron radiation permits observation of luminescence kinetics across a time scale from tens of picoseconds to milliseconds and beyond. Novel types of luminescence, including many-body effects and cross-luminescence, will be studied. The information generated through this work will undoubtedly be of importance in establishing the best type of material to be used in a wide range of commercially important imaging devices, including scintillators.
