Abstract

Computational and experimental methodology is employed to study optical properties in Eu-doped BaAl2O4 phosphors. The symmetry and detailed geometry of the Eu-dopant site, predicted by atomistic simulation, are used to calculate the crystal field parameters and the intensity parameters (O2 and O4) based on a Judd-Ofelt approach to the Eu3+ ion. The phenomenological intensity parameters are obtained from the emission spectra of the Eu-doped BaAl2O4 and compared to the theoretical results. Experimental and calculated values for the 7F1 energy sub-levels of the Eu3+ and maximum Stark splittings (?Emax) are also obtained.
