Dr. Latif Ullah Khan | Spectroscopy | Best Researcher Award

Beamline Scientist at Synchrotron-light for Experimental Science and Applications in the Middle East (SESAME), Jordan

Dr. Latif Ullah Khan is a highly accomplished researcher and beamline scientist with expertise in the field of X-ray absorption spectroscopy (XAS) and its applications in material science and nanotechnology. He has a diverse academic background with a BSc from Gomal University, Pakistan, an MSc in Chemistry from the University of Peshawar, Pakistan, and a MS/Doctorate in Inorganic Chemistry from the Institute of Chemistry at USP, São Paulo, Brazil. Dr. Khan’s research focuses on gaining insights into the energy levels, electronic and local atomic structure order of metal sites in lanthanides (f-block elements) materials, and quantum-confined semiconductors at reduced dimensions. He utilizes XAS and optical spectroscopy in correlation with X-ray excited optical luminescence (XEOL) to understand the fundamental emission mechanism of these materials, with applications in advanced technologies such as light-emitting diodes, display devices, catalysis, renewable energy, and bio-imaging. As a beamline scientist, Dr. Khan has developed an experimental station for XEOL at the BM08-XAFS/XRF beamline, where he employs XEOL in combination with XANES to elucidate the luminescence mechanism and explore the X-ray scintillation properties of novel nanophosphors. He is also involved in designing a von Hamos X-ray emission spectrometer (XES) at the XAFS/XRF beamline experimental station.

📊Research  Interest:

Dr. Latif Ullah Khan’s research focuses on gaining insight into the energy levels, electronic and local atomic structure order of metal sites in lanthanides (f-block elements) materials, and quantum-confined semiconductors (e.g., CdTe, CdS, ZnS, Ag2S, etc.) at reduced dimensions, such as 0D nanocrystals, 1D nanowires, and 2D flakes. He uses X-ray absorption spectroscopy (XAS) and optical spectroscopy in correlation with X-ray excited optical luminescence (XEOL) to understand their fundamental emission mechanism from UV-visible to near-infrared spectral regions. His research is strongly driven by their future applications in advanced technologies, such as light-emitting diodes, display devices, data storage, catalysis, renewable energy, information technologies, sensing, bio-imaging, and photothermal therapy in biomedicine. As a beamline scientist, he developed an experimental station for XEOL at the BM08-XAFS/XRF beamline, employing XEOL in combination with XANES to elucidate the luminescence mechanism and explore the X-ray scintillation properties of novel nanophosphors. He probes the local atomic structure of inorganic materials and complexes via XANES simulation and EXAFS fit, using modern data science machine/deep learning approaches (PyFitit library package and FDMNES/feff codes) in the high-level programming language Python and Artemis/Athena from Demeter, respectively. Dr. Latif Ullah Khan also works with the BM08-XAFS/XRF beamline staff and collaborates with Dr. Santiago Figueroa from QUATI XAFS beamline SIRIUS LNLS Brazil and Dr. Grigory Smolentsev from Paul Scherrer Institut (PSI) on designing a von Hamos X-ray emission spectrometer (XES) at the XAFS/XRF beamline experimental station.
