Annealing effects on luminescent properties of Eu3+ doped Gd2Zr2O7 nanopowders

Preparation and Scintillating Properties of Sol-Gel Eu3+, Tb3+ Co-Doped Lu2O3 Nanopowders

Nanocrystalline Eu(3+), Tb(3+) co-doped Lu(2)O(3) powders with a maximum size of 25.5 nm were prepared by the sol-gel process, using lutetium, europium and terbium nitrates as precursors, and ethanol as a solvent. Differential thermal analysis (DTA) and infrared spectroscopy (IR) were used to study the chemical changes during the xerogel annealing. After the sol evaporation at 100 °C, the forme...

Study on luminescent properties of Eu3+ doped new type yttrium tungsten oxide nanophosphors.

In this paper, a novel nanophosphor, Y10W2O21:Eu, was synthesized through co-precipitation which is a simple and low-costing method. The structure and morphology of the nanocrystal samples were characterized by using XRD and FE-SEM. The emission spectra, excitation spectra and fluorescence decay curves were measured. J-O parameters, quantum efficiencies of Eu3+ 5D0 energy level, color coordinat...

Synthesis and luminescent properties of Ln3+ (Eu3+, Sm3+, Dy3+)-doped lanthanum aluminum germanate LaAlGe2O7 phosphors

The novel phosphor of LaAlGe2O7 activated with the trivalent rare-earth Ln3+ (Ln = Eu, Sm, Dy) ions were synthesized by solid-state method, nd their characterization and luminescent properties were investigated. The absorption, emission and excitation spectra, and decay curves were mployed to study the luminescence properties. The calcined powders of the Eu3+, Sm3+ and Dy3+ ions doped in the La...
