Dorenbos, P. (author), Bos, A.J.J. (author), Poolton, N.R.J. (author)We studied charge carrier trapping, detrapping, and recombination phenomena in Ce3+ doped YPO4, codoped with Sm3+, Dy3+, or Tm3+. Ce ions trap the holes and Sm, Dy, and Tm trap electrons created during x-ray irradiation. By means of red to infrared stimulation, the trapped electrons can be back transferred to Ce leading to shorter wavelength Ce3...journal article 2010

Drozdowski, W. (author), Dorenbos, P. (author), Drozdowska, R. (author), Bos, A.J.J. (author), Poolton, N.R.J. (author), Tonelli, M. (author), Alshourbagy, M. (author)In this paper we present the studies performed on a set of Lu3Al5O12:Pr (LuAG:Pr) crystals with praseodymium concentration between 1.5 and 10%, grown by the micro-pulling-down (muPD) technique. The research comprises the measurements of X-ray excited emission spectra and 137Cs gamma-ray pulse height spectra in a range from 78 to 600 K, and...journal article 2009
