Computational and experimental methods are employed to study the optical properties of Dy-doped BaAl2O4 matrix. Atomistic modelling is used to make predictions of Dy doping sites and charge compensation schemes. The symmetry predicts from atomistic modeling was used to calculate crystal field parameters and to obtain the energies of the electronic transitions of the Dy3+ ion. Dy-doped BaAl2O4 was...
Radioluminescence (RL) emissions were obtained for the BaZrO 3 self-assembled nanocrystals under decaoctahedral shape, if produced via microwave-assisted hydrothermal method. Trapped F centers created within the band gap are the result of order–disorder effects, which act as key factors supporting significant RL emission through a detrapping process. The influences of size and morphology on...
