It concerns the conversion of the X-ray energy absorbed by the system to optical photons often involving multi-step cascade processes. XEOL is often used together with XANES/NEXAFS to provide site specificity which in turn can help reveal the electronic structure and optical properties of the system of interest.<br /> <br /> XEOL can be studied in the time domain if a pulsed X-ray source is used. It is possible to use the time structure of a synchrotron radiation source to study the decay dynamics of a system ''via'' various optical de-excitation pathways. This technique is called '''time-resolved X-ray excited optical luminescence'''.<br /> <br /> == See also ==<br /> *[[Secondary process detection]]<br /> *[[X-ray absorption fine structure (XAFS)|XANES/NEXAFS]]<br /> <br /> [[Category:X-ray absorption spectroscopy]]</div>
