Luminescence Spectra of Mn 2 + Doped in
Luminescence data for 6 manganese doped langbeinites, Aj B2 + (S04)3 , are reported. They are consistent with octahedral symmetry of the impurity center (substitutional in B site), although for the host lattice the B site is known to show three-fold axial (distorted octahedral) symmetry only. In accordance with previous conclusions from EPR data the luminescence parameters indicate structural r...
متن کاملMn-doped ZnS nanoparticles as efficient low-voltage cathodoluminescent phosphors
We have synthesized nanoparticles of ZnS doped with Mn for potential use as cathodoluminescent phosphors in field-emission displays ~FEDs!. We show that the cathodoluminescent efficiency of particles <100 nm in diameter is within 40% of that of a commercial ~micron-sized! phosphor when the electron-beam energy ranges between 500 and 3500 eV. The nanoparticles exhibit less current saturation tha...
متن کاملWater-based route to colloidal Mn-doped ZnSe and core/shell ZnSe/ZnS quantum dots.
Relatively monodisperse and highly luminescent Mn(2+)-doped zinc blende ZnSe nanocrystals were synthesized in aqueous solution at 100 °C using the nucleation-doping strategy. The effects of the experimental conditions and of the ligand on the synthesis of nanocrystals were investigated systematically. It was found that there were significant effects of molar ratio of precursors and heating time...
متن کاملDetoxification of Aflatoxin-Contaminated Maize by Neutral Electrolyzed Oxidizing Water
Aflatoxins, a group of extremely toxic mycotoxins produced by Aspergillus flavus, A. parasiticus and A. nomius, can occur as natural contaminants of certain agricultural commodities, particularly maize. These toxins have been shown to be hepatotoxic, carcinogenic, mutagenic and cause severe human and animal diseases. The effectiveness of neutral electrolyzed oxidizing water (NEW) on aflatoxin d...
متن کاملIsolation and Characterization of an Azo Dye Reactive Red 2 Degrading Bacteria from Dye Contaminated Soil
A bacterial strain GSM3, capable of decolorizing an azo dye Reactive Red 2 was isolated from dye contaminated soil sample collected from Ammu dyeing industry, Bellary, India. Based on phenotypic characteristics and 16S rDNA sequencing, strain GSM3 was identified as Pseudomonas aeruginosa GSM3. Isolate GSM3 showed 97% decolorization of Reactive Red 2 (300 mgL) within 10 h, while maximally it cou...
