  • Charge Carriers in Commercial Photocatalysts : Fractal Kinetics and Effect of “Inert” Additives 
    Günnemann, Carsten; Curti, Mariano; Sieland, Fabian; Bahnemann, Detlef W. (Dordrecht : Springer Science + Business Media, 2021)
    High photon conversion efficiencies and low-cost materials are crucial for implementing photocatalytic solutions in large scale applications. To improve the conversion efficiencies, knowledge on the lifetime and dynamics ...
  • Complex formation between UO22+ and α-isosaccharinic acid: insights on a molecular level 
    Brinkmann, Hannes; Patzschke, Michael; Kaden, Peter; Raiwa, Manuel; Rossberg, André; Kloditz, Roger; Heim, Karsten; Moll, Henry; Stumpf, Thorsten (London : Royal Society of Chemistry, 2019)
    Cellulosic materials present as tissue, paper, wood, or filter materials in low and intermediate level waste will degrade under alkaline conditions if water ingresses in a cementitious backfilled repository. The main ...
  • Core-shell particles as efficient broadband absorbers in infrared optical range 
    Evlyukhin, Andrey B.; Nerkararyan, Khachatur V.; Bozhevolnyi, Sergey I. (Washington, DC : OSA - The Optical Society, 2019)
    We demonstrate that efficient broadband absorption of infrared radiation can be obtained with deeply subwavelength spherical dielectric particles covered by a thin metal layer. Considerations based on Mie theory and the ...
  • Experimental Determination of the Uncertainty of the Absorption Coefficient of Crystalline Silicon 
    Schinke, Carsten; Peest, Peter Christian; Bothe, Karsten; Schmidt, Jan; Brendel, Rolf; Vogt, Malte R.; Kröger, Ingo; Winter, Stefan; Schirmacher, Alfred; Lim, Siew; Nguyen, Hieu T.; MacDonald, Daniel (Amsterdam : Elsevier, 2015)
    Based on a combined analysis of spectroscopic ellipsometry, reflectance and transmittance measurements as well as spectrally resolved luminescence measurements and spectral responsivity measurements, we present data of the ...
  • FPGA based laser frequency stabilization using FM spectroscopy 
    Spindeldreier, Christian; Bartosch, Wolfgang; Wendrich, Thijs; Rasel, Ernst Maria; Ertmer, Wolfgang; Blume, Holger (Bellingham, Wash. : SPIE, 2018)
    Frequency stabilized light sources with narrow linewidth are mandatory for atom interferometry based experiments. For compact experiment designs used on space platforms, tunable DFB diode lasers are often used. These lasers ...
  • Synthesis of visible light driven TiO2 coated carbon nanospheres for degradation of dyes 
    Raza, Waseem; Haque, M.M.; Muneer, M.; Bahnemann, Detlef W. (Amsterdam : Elsevier, 2016)
    Herein, we report the successful synthesis of visible light driven metal doped TiO2 coated carbon nanospheres (CNS) via a facile hydrothermal approach. The synthesized materials were characterized by standard analytical ...
  • Temperature dependence of the band gap of 28Si:P at very low temperatures measured via time-resolved optical spectroscopy 
    Sauter, E.; Abrosimov, N.V.; Hübner, J.; Oestreich, M. (College Park, MD : APS, 2023)
    We measure the temperature dependence of the indirect band gap of isotopically purified 28Si:P in the regime from 0.1 K to 3 K by high-resolution absorption spectroscopy of the donor bound exciton transition. The measurements ...
