In this study, we exhibit clearly the capabilities of combing X-ray excited optical luminescence (XEOL), Time-resolved XEOL and Hanbury-Brown and Twiss (HB-T) interferometer in Taiwan Photon Source (TPS) 23A X-ray nanoprobe beamline. TPS 23A X-ray nanoprobe is a multi-functional hard X-ray beamline with good spatial and time resolution capabilities. Its energy range is 5-13.5 keV, and it can provide an X-ray beam spot size of about 100 nm. Base on the excellent spatial resolution using the nanofocused beam, the emission distributions of the artificial micro diamonds can be obtained through XEOL map, as well as the featured emission peaks of the selected local area can be shown by the XEOL spectra. The hybrid bunch mode of TPS can provide not only a sufficiently high peak power density for the experiments of each beamline, but also high-quality temporal domain (~ 200 ns) measurements for studying the dynamic luminescence of photonic materials. Furthermore, the XEOL spectra of the artificial micro diamonds can be studied by the HB-T interferometer to identify the properties of the single photon sources. Using TPS 23A X-ray nanoprobe in conjunction with XEOL, TR-XEOL and HB-T allows us to deterministically create and measure single photon sources in a range of materials systems with nanometer resolution.
