Luminescent Eu3+-doped NaLa(WO4)(MoO4) and Ba2CaMoO6 prepared by the modified Pechini method

Structural and Luminescent Properties of Eu2+-doped Aluminates Prepared by the Sol-gel Method.

Alkaline earth aluminates with the overall nominal compositions Mg0.5Sr0.5Al2O4 (MSA), Ca0.5Sr0.5Al2O4 (CSA) and Ca0.5Mg0.5Al2O4 (CMA) doped with 0.5 or 1 mol% of Eu2+ ions were obtained by a modified aqueous sol-gel method and annealed in a reductive atmosphere at 900, 1000, 1100 and 1300 °C. The sample compositions and their structures were studied by XRD employing the Rietveld method. Solid ...

Structural and Luminescence Properties of Lu2O3:Eu3+ F127 Tri-Block Copolymer Modified Thin Films Prepared by Sol-Gel Method

Lu₂O₃:Eu3+ transparent, high density, and optical quality thin films were prepared using the sol-gel dip-coating technique, starting with lutetium and europium nitrates as precursors and followed by hydrolysis in an ethanol-ethylene glycol solution. Acetic acid and acetylacetonate were incorporated in order to adjust pH and as a sol stabilizer. In order to increment the thickness of the films a...

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...
