Selling, J. (author), Schweizer, S. (author), Birowosuto, M.D. (author), Dorenbos, P. (author)Single crystals of Ce-activated BaCl2, BaBr2, and BaI2 were investigated under x-ray and ?-ray excitation. The Ce3+-related x-ray excited luminescence in BaBr2 shifts significantly to longer wavelengths upon increasing the doping level from 0.1% to 1%. In Ce-activated BaCl2 only a slight shift can be observed. BaI2 does not show any Ce3+-related...journal article 2007

(author)The phosphors Ba3Gd(BO3)3:Ce3+ were prepared by a solid-state reaction technique at high temperature. The vacuum ultraviolet-ultraviolet and visible spectroscopic properties of the phosphors together with decay time curves are investigated and discussed. The spectroscopic properties are explained by occupancy of Ce3+ at two different Gd sites in...journal article 2007

Van der Kolk, E. (author), De Haas, J.T.M. (author), Bos, A.J.J. (author), Van Eijk, C.W.E. (author), Dorenbos, P. (author)A combined photoconductivity, absorption, and thermoluminescence study was performed to understand the absence of luminescence from Ce3+ in LaAlO3:Ce3+. It is demonstrated that the absence of luminescence is the result of Ce3+ ionization from the 5d excited states, which are all located in the conduction band. Ce3+ ionization is accompanied by...journal article 2007

(author)Scintillation and luminescence characteristics of Rb2LiYBr6 doped with 0.1%, 0.5%, 1%, and 5%?Ce3+ are presented. Under optical and x-ray excitation, Ce3+ doublet emission is observed at 385 and 420 nm. Rb2LiYBr6:0.5%?Ce3+ shows very high thermal neutron scintillation light output of 83?000 photons/neutron. An excellent neutron peak resolution...journal article 2007

Selling, J. (author), Birowosuto, M.D. (author), Dorenbos, P. (author), Schweizer, S. (author)Single crystals of undoped or europium-doped barium chloride, bromide, and iodide were investigated under x-ray and ?-ray excitations. The Eu2+-related x-ray excited luminescence found in the Eu-doped barium halides occurs at 402, 404, and 425?nm for the chloride, bromide, and iodide, respectively. BaCl2:Eu2+ shows the best scintillation...journal article 2007

Dorenbos, P. (author), Van der Kolk, E. (author)Knowledge from lanthanide spectroscopy on wide band gap (6–10?eV) inorganic compounds is used to understand and predict optical and electronic properties of the lanthanides in the III-V semiconductor GaN. For the first time the location of the 4fn ground state energy of each divalent and trivalent lanthanide ion relative to the valence and...journal article 2006

Birowosuto, M.D. (author), Dorenbos, P. (author), Van Eijk, C.W.E. (author), Krämer, K.W. (author), Güdel, H.U. (author)In this paper, we investigated the scintillation properties of LuI3:Ce3+. Radioluminescence, light output, energy resolution, and ?-scintillation decay are reported. We find an extremely high light output of 98?000±10?000?photons/MeV. LuI3:Ce3+ also gives a very high electron-hole (e-h) pair response when it is coupled with an avalanche...journal article 2006

Dorenbos, P. (author)A mechanism of persistent luminescence that was proposed in 1996 for SrAl2O4:Eu2+;Dy3+ has been widely adopted to explain afterglow in many Eu2+ and Dy3+ codoped aluminates and silicates. The mechanism involves the thermally activated release of a hole from Eu2+ in its excited 5d state to the valence band which is subsequently trapped by Dy3+....journal article 2005
