Pure cubic phase ultra-small a-NaYF 4 :4 % Eu 3? colloidal nanoparticles were synthesized by thermal decomposition reaction using three various capping ligands, i.e., oleic acid, trioctylphosphine oxide, and hexadecylamine. To expose as many Eu 3? ions as possible to interactions with the surface-bounded ligands, the nanoparticles were fabricated to have(More)
Lanthanide-doped nanoparticles are of considerable interest for biodetection and bioimaging techniques thanks to their unique chemical and optical properties. As a sensitive luminescence material, they can be used as (bio) probes in Förster Resonance Energy Transfer (FRET) where trivalent lanthanide ions (La3+) act as energy donors. In this paper we present(More)
Gold nanoparticles (Au NPs) were prepared by direct current atmospheric pressure glow microdischarge (dc-lAPGD) generated between a miniature argon flow microjet and a flowing liquid cathode. The applied discharge system was operated in a continuous flow liquid mode. The influence of various stabilizers added to the solution of the liquid cathode, i.e.,(More)

A direct current atmospheric pressure glow microdischarge (dc-µAPGD) generated between an Ar nozzle microjet and a flowing liquid was applied to produce Au-Ag core-shell nanoparticles (Au@AgCSNPs) in a continuous flow system. Firstly, operating dc-µAPGD with the flowing solution of the Au(III) ions as the cathode, the Au nanoparticles (AuNPs) core was(More)
The synthesis, morphological characterization , and optical properties of colloidal, Eu(III) doped Gd 2 O 3 nanoparticles with different sizes and shapes are presented. Utilizing wet chemical techniques and various synthesis routes, we were able to obtain spherical, nanodisk, nanotripod, and nanotri-angle-like morphology of Gd 2 O 3 :Eu 3? nanoparticles.(More)
