Abstract: Background

X-ray excited optical luminescence (XEOL) is an X-ray photon-in, optical photon-out technique that detects ultraviolet to near infrared (200~900 nm) photons emitted by the sample under soft X-ray excitation. Combining with synchrotron radiation, XEOL can be used to identify the origin of the luminescence and study luminescence dynamics.


This study aims to build a soft X-ray excited steady-state and transient luminescence detection system at the soft X-ray beamline BL08U1A of Shanghai Synchrotron Radiation Facility (SSRF).


A data acquisition system was developed independently to realize the simultaneous detection of XEOL and total electron yield (TEY) spectra under different soft X-ray photon energies. A spectrometer, and a set of subsystems, including timing, nuclear electronics and motion control were integrated to realize time-resolved XEOL (TRXEOL) detection. Finally, experimental tests were performed to verify performance of this detection system.


The XEOL and TEY signals at the Cs M4, 5 absorption edges of CsPbI3 submicron wires were detected, and the effect of photonic crystals on the output of scintillators was studied. The time-resolved XEOL spectra and decay curves of zinc oxide were obtained by TRXEOL detection system.


The results verified the feasibility of XEOL/TRXEOL detection system at the soft X-ray experimental station BL08U1A which provides a good technical means for studying the luminescent mechanism and luminescent dynamics of materials at SSRF.
