Porphyrin nanorods were prepared by ion-association between free-base meso 5,10,15,20-tetrakis-(4-[Formula: see text]-methylpyridinium)porphyrin cations and tetraphenylborate anions. The nanorods have variable lengths (up to a few micrometers long) and diameters ([Formula: see text]50–500 nm). Their structure at the molecular level was elucidated by combining multinuclear solid state NMR spectroscopy, synchrotron X-ray powder diffraction and DFT calculations.

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.

Red Emitting Phosphor

Ca9Y(PO4)7:Sm3+ phosphor was prepared via solid state reaction. The crystal structure of the phosphor was characterized by X-ray powder diffraction (XRD). The photoluminescence (PL) properties of Ca9Y(PO4)7:Sm3+ were investigated. The emission of the Ca9Y(PO4)7:Sm3+ phosphor consisted of some sharp emission peaks of Sm3+ centered at 563 nm, 600 nm, and 647 nm. The strongest one is located at 600 nm due to the 4G5/2–6H7/2 transition of Sm3+. The critical distance was calculated to be 10.5 Å. The chromatic properties of the sample Ca9Y(PO4)7:Sm3+ phosphor were located in the orange reddish region. The Ca9Y(PO4)7:Sm3+ phosphor may be potentially used as red phosphor for white light-emitting diodes (WLED).
