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 Ω_2,4 of Eu³⁺ in the SrAl₂O₄ matrix were calculated.
