  • Charge traps in Ce-doped CaF2 and BaF2 
    Drozdowski, Winicjusz; Przegiętka, Krzysztof; Wojtowicz, Andrzej J.; Oczkowski, Hubert Lucjan (Institute of Physics, Polish Academy of Sciences, 1999)
    Thermoluminescence of CaF2:Ce, BaF2, and BaF2:Ce irradiated at room temperature is reported. X-ray induced emission spectra of the samples show that both excitonic (due to e- + VK recombination) and Ce3+ d-f luminescence ...
  • Dosimetric features of strontium orthosilicate (Sr2SiO4) doped with Eu2+ 
    Barzowska, Justyna; Chruścińska, Alicja; Przegiętka, Krzysztof; Szczodrowski, Karol (Elsevier B.V., 2014)
    Thermoluminescence (TL) of strontium orthosilicate doped with Eu2+ has been investigated in the range RT- 750 K. Trap parameters of a TL peak at 450 K established by means of glow curve analysis suggest the possibility of ...
  • Luminescence from beta-Irradiated graphene layers 
    Chruścińska, Alicja; Przegiętka, Krzysztof; Szroeder, Pawel; Oczkowski, Hubert Lucjan; Rozploch, Franciszek (Instytut Fizyki PAN, 2006)
    We found that beta-irradiated samples of crystallite graphite and multi--walled carbon nanotubes emit light during heating above room temperature. This behaviour is rather surprising for semimetals. Due to the lack of deep ...
  • Quartz TL decay due to optical bleaching 
    Chruścińska, Alicja; Przegiętka, Krzysztof (WIND, 2005)
    In spite of many years of research our knowledge of the traps responsible for the OSL in quartz is not complete. Many papers report the complexity of this signal, determine its components and discuss their usefulness for ...
  • Trap spectra of annealed quartz 
    Chruścińska, Alicja; Oczkowski, Hubert Lucjan; Przegiętka, Krzysztof (Institute of Physics, Polish Academy of Sciences, 1996)
    The trap energy density spectra of natural quartz were investigated by the fractional glow technique. The thermal treatment before excitation induces the changes of thermoluminescence sensitivity as well as the changes of ...
