Luminescent properties of novel red-emitting phosphor: Gd2O2CN2:Eu3+

Eu 3+ -doped Gd2O2CN2 was firstly synthesized by a classical solid-state reaction of Li2CO3, Eu2O3 and GdF3 under NH3 gas flow in the presence of graphite at low firing temperature. Powder X-ray diffraction (XRD) analysis indicated that Gd2O2CN2: Eu 3+ crystallizes in a trigonal-type structure with space group P-3m1. Gd2O2CN2: Eu 3+ shows a sharp red emission band peaking at 626 nm under excita...

Luminescent Properties of Calcium Halophosphate Phosphor for White Light Emitting Diode

Tb 3+ and Eu 3+ activated Ca5(PO4)Cl phosphors were synthesized by a solid state reaction. From powder X-ray diffraction analysis, Ca5(PO4)Cl with a hexagonal structure was confirmed. The excitation spectra indicate the phosphor can be excited by near ultraviolet (NUV) light, which makes it attractive for white light emitting diode (WLED) applications. When the phosphor was excited by 394 nm li...

A europium complex with enhanced long-wavelength sensitized luminescent properties.

We report a new complex Eu(tta)(3).bpt (tta = thenoyltrifluoroacetonate; bpt = 2-(N,N-di-ethylanilin-4-yl)-4,6-bis(pyrazol-1-yl)-1,3,5-triazine) with excellent long-wavelength sensitized luminescent properties, in which four hydrogen atoms replace the methyl groups at the 3,3'- and 5,5'-positions of the pyrazolyl rings in a previously reported complex Eu(tta)(3).dpbt. Upon visible-light excitat...

Raman Spectra of Luminescent Graphene Oxide (GO)-Phosphor Hybrid Nanoscrolls

Graphene oxide (GO)-phosphor hybrid nanoscrolls were synthesized using a simple chemical method. The GO-phosphor ratio was varied to find the optimum ratio for enhanced optical characteristics of the hybrid. A scanning electron microscope analysis revealed that synthesized GO scrolls achieved a length of over 20 μm with interior cavities. The GO-phosphor hybrid is extensively analyzed using Ram...

Synthesis, Characterization, Luminescent Properties, And Crystal Structure Determination Of a New Platinium (IV) Complexe : trans-[Pt(4-mpy)2Cl4]

The new trans-[Pt(4-mpy)2Cl4] (1) complex (4-mpy is 4-methylpyridine) was prepared from the reaction of H2PtCl6.6H2O with 4-methylpyridine in methanol. Synthesized complex was thoroughly characterized by elemental analysis, IR and 1H-NMR spectroscopy.Elemental analysis data (C, H, N) support the general composition of the title complex and the structure have been established by single-crystal X...
