Magnetoresistance Characteristics in Individual Fe₃O₄ Single Crystal Nanowire

Sub-two nanometer single crystal Au nanowires.

Ultrathin single crystal Au nanowires with diameter of approximately 1.6 nm and length of few micrometers were synthesized with high yield by simply mixing HAuCl 4 and oleylamine at room temperature. High resolution transmission electron microscopy studies revealed that all of these nanowires are single crystalline and grew along the [111] direction. The valency evolution of the gold species du...

Random lasing in Nd:LuVO4 crystal powder.

Room temperature random lasing action is demonstrated for the first time in a low concentrated neodymium doped vanadate crystal powder. Laser threshold and emission efficiency are comparable to the ones obtained in stoichiometric borate crystal powders. The present investigation provides a complete picture of the random lasing characteristics of Nd-doped vanadate powder both in the spectral and...

Synthesis and Characterization of Tb[N(CN)₂]₃·2H₂O and Eu[N(CN)₂]₃·2H₂O: Two New Luminescent Rare-Earth Dicyanamides

Two new rare-earth dicyanamides, namely, Tb[N(CN)2]3‚2H2O and Eu[N(CN)2]3‚2H2O, have been prepared by ion exchange in aqueous solution, followed by evaporation of the solvent at room temperature. The structures of both compounds have been solved and refined from single-crystal and powder X-ray diffraction data, respectively. The two compounds are isostructural and are built up from irregular qu...
