Spectroscopy study of SrAl2O4:Eu3+

Computational and experimental method is employed to study optical properties SrAl2O4 induced by europium dopant. Atomistic modeling is used to predict the doping sites and charge-compensation schemes for SrAl2O4:Eu systems and also to calculate the symmetry and the detailed geometry of the dopant site. This information is then used to calculate the crystal field parameters. SrAl2O4 doped with europium were prepared via a sol–gel proteic methodology. The photoluminescence experiments were performed at room temperature and at 13 K. The transition energy for the Eu3+-doped material is compared to the theoretical results. Based on Judd-Ofelt approach, the intensity parameters Ω2,4 of Eu3+ in the SrAl2O4 matrix were calculated.
