    • Time-resolved photoluminescence study of CdSe/CdMnS/CdS core/multi-shell nanoplatelets 

      Murphy, J. R.; Delikanli S.; Scrace, T.; Zhang, P.; Norden, T.; Thomay, T.; Cartwright, A. N.; Demir, Hilmi Volkan; Petrou, A. (American Institute of Physics Inc., 2016)
      We used photoluminescence spectroscopy to resolve two emission features in CdSe/CdMnS/CdS and CdSe/CdS core/multi-shell nanoplatelet heterostructures. The photoluminescence from the magnetic sample has a positive circular ...
    • Ultra-low noise fiber laser systems and their applications 

      Budunoğlu, İbrahim Levent (Bilkent University, 2014)
      Fiber laser systems are intensely studied for and already utilized in a wide range of scientific, biomedical and industrial applications. Scientifically, fiber lasers are widely used for spectroscopy, laser-matter ...
    • Ultrafast transient optical loss dynamics in exciton-plasmon nano-assemblies 

      Elkabbash, M.; Rashed, A.R.; Kucukoz, B.; Nguyen, Q.; Karatay, A.; Yaglioglu, G.; Özbay, Ekmel; Caglayan, H.; Strangi, G. (Royal Society of Chemistry, 2017)
      We study the exciton-plasmon dynamics that lead to optical loss mitigation via ultrafast transient absorption spectroscopy (UTAS) on hybrid aggregates of core-shell quantum dots (QDs) and Au nanoparticles (NPs). We highlight ...
    • Universal infrared absorption spectroscopy using uniform electromagnetic enhancement 

      Ayas S.; Bakan, G.; Ozgur E.; Celebi, K.; Dana, A. (American Chemical Society, 2016)
      Infrared absorption spectroscopy has greatly benefited from the electromagnetic field enhancement offered by plasmonic surfaces. However, because of the localized nature of plasmonic fields, such field enhancements are ...
    • XPS characterization of Bi and Mn collected on atom-trapping silica for AAS 

      Süzer, Şefik; Ertas, N.; Ataman, O. Y. (Sage Publications, Inc., 1999)
      The chemical state of analyte species collected on a water-cooled silica tube during atom-trapping atomic absorption spectrometric determination is investigated with the use of X-ray photoelectron spectroscopy (XPS) for ...
