Well Shaped Mn3O4 Nano-octahedra with Anomalous Magnetic Behavior and Enhanced Photodecomposition Properties Very uniform and well shaped Mn3O4 nano-octahedra are synthesized using a simple hydrothermal method under the help of polyethylene glycol (PEG200) as a re... Y Li,H Tan,XY Yang,......
As it was found, the two mechanisms of electroluminescence (EL) excitation are characteristic for Zn_2GeO_4:Mn thin film electroluminescent structures: direct impact excitation of Mn~(2+) ions by field-heated electrons and by field-ionized sensitizer defect, which after the nonradiative ...

A new electroluminescent phosphor, Zn2GeO4Mn2++SiC whiskers, is proposed.A procedure is described to fabricate a solid sample of this composite material.Under an AC voltage, green light is emitted only in samples containing the SiC whiskers.A brightness of 25Cd/m2and efficiency of 0.25Lm/W ...
We synthesized Zn2GeO4:Mn2+ phosphors using MnO2 as manganese source material by a solid state reaction in air condition. The Zn2GeO4:Mn2+ phosphors show green emission band corresponding to the (4)T(1)(6)A(1) transitions of Mn2+. The green emission of Zn2GeO4:Mn2+ phosphors gives...
