NdSr 2 RuCu 2 O x material has been prepared as polycrystalline powder by solid state reaction. The compound has been investigated by synchrotron x-ray powder diffraction and scanning electron microscopy. The experimental results show that the average crystal structure is a disordered cubic perovskite with Nd and Sr cations occupying the same site and the same substitution is found for Cu and Ru atoms. A comparison between the crystal structure and morphology of this compound and the superconducting tetragonal GdSr 2 RuCu 2 O 8 is also discussed.

Electroluminescence Intensity

Tb2O3:Er light-emitting diodes were prepared by radio-frequency magnetron sputtering method and the EL performance of the devices were studied. The crystal structure and morphology of the annealed films were investigated by XRD and SEM, respectively. The EL spectrum was achieved and the EL principle was discussed. Six emission peaks of Er[Formula: see text] located at 402, 517, 548, 649, 691, and 1,538[Formula: see text]nm were observed, achieving energy transfer from Tb[Formula: see text] to Er[Formula: see text]. In order to study the effect of Er+ doping concentration, the doping concentrations of Tb2O3:Er films were from 5[Formula: see text]at.% to 20[Formula: see text]at.%. The effect on electroluminescence intensity of doping concentration was investigated and the optimal doped concentration was 15[Formula: see text]at. %.
