Antimony(III)-doped PbWO4 crystals with enhanced photoluminescence via a shape-controlled sonochemical route

Article Abstract:

A facile, Pluronic P123 (EO20PO70EO20)-assisted, sonochemical method is used to synthesize Sb(III)-doped lead tungstate single crystals with controlled shapes and enhanced green emission. Room-temperature photoluminescence of doped PbWO4 samples with different morphologies at desired Sb doping concentrations have indicated greatly enhanced luminescence intensity compared to the undoped PbWO4.

Cyclic voltammetric study of intramolecular and intermolecular hypervalent organoantimony complexes with Sb...N bonding

Article Abstract:

The electrochemical behaviors of a series of four intramolecular hypervalent complexes containing Sb...N bonding (antimony (III, V) compounds) and of the relevant common precursors, organonitrogen and (tri- and penta-) substituted stibines, are investigated using cyclic voltammetry. Further, description about the detailed analysis of the oxidation current that took place is presented.
