Luo, H. (author), bos, A.J.J. (author), Dorenbos, P. (author)Two different charge carrier trapping processes have been investigated in RE2O2S:Ln3+ (RE = La, Gd, Y, and Lu; Ln = Ce, Pr, and Tb) and RE2O2S:M (M = Ti4+ and Eu3+). Cerium, praseodymium and terbium act as recombination centers and hole trapping centers while host intrinsic defects provide the electron trap. The captured electrons released from...journal article 2017

Luo, H. (author), Ning, Lixin (author), Dong, Yuanyuan (author), bos, A.J.J. (author), Dorenbos, P. (author)Photoluminescence excitation (PLE) and emission spectra (PL) of undoped (Sr, Ca)<sub>3</sub>(Y, Lu)<sub>2</sub>Ge<sub>3</sub>O<sub>12</sub> as well as Eu<sup>3+</sup>- and Ce<sup>3+</sup>-doped samples have been investigated. The PL spectra show that Eu<sup>3+</sup> enters into both dodecahedral (Ca, Sr) and octahedral (Y, Lu) sites. Ce<sup>3...journal article 2016
