Luminescence Properties of Europium Activated SrIn2O4. — SrIn2-xO4:xEu
= 0.01, 0.02, 0.04) compounds are prepared by solid state reactions of stoichiometric
29- 013 (x
mixtures of SrCO3, In2O3, and Eu2O3 (950 °C, 70 h). The samples are characterized by
powder XRD, IR and Raman, luminescence, and excitation spectroscopy. SrIn2O4 crystallizes in the orthorhombic space group Pnam with Z = 4. In the Eu doped samples Eu
ions occupy both Sr and In positions leading to blue broad band luminescence centered
at 480 nm and the sharp f—f transitions associated with Eu2+ and Eu3+ ions, respectively. — (BASZCZUK*, A.; JASIORSKI, M.; NYK, M.; HANUZA, J.; MACZKA, M.;
