Phenanthroline Monohydrate

Rare earth fluorescent complexes monomer with activated double bonds was synthesized by using Eu as the central atom, Methacrylic acid and 1, 10-Phenanthroline monohydrate as ligand. The structure of resultant Eu (MAA)3Phen was determined by infrared spectrum, ultraviolet spectrum and element analysis, and the fluorescence property of the complexes was tested by fluorescence spectra and fluorescence microscopy. Compared with conventional luminescent materials, this resultant complexes show greater fluorescence intensity. The analysis has revealed that with the increase of rare earth ion concentration from 4×10-5mol·L-1 to 4×10-3mol·L-1, the fluorescence quenching phenomenon appeared in the complexes solution.

Upconversion Nanocrystals

AbstractHighly photochemically stable nanoparticles, in which upconversion luminescence can be excited – so-called upconversion nanocrystals (UC-NCs) – exhibit widely separated (up to 500 nm) narrow luminescence bands in the visible (VIS) region located far from the excitation near-infrared (NIR) laser radiation, and thus can be more easily identified compared to organic luminophores and semiconductor nanoparticles. Due to a deep penetration of exciting infrared (IR) radiation, the absence of parasitic fluorescence of biomolecules and the absence of phototoxicity and photobleaching upon near IR excitation, UC-NCs can be efficiently used as fluorescent probes in biological studies and fluorescence diagnostics (FD). The doping of such nanoparticles with GdWe studied the upconversion characteristics of inorganic nanoparticles made of different materials doped with rare-earth ion (REI) pairs YbBased on the results obtained, the matrix LaThe investigated complex polycrystalline oxide compounds are promising as diagnostic agents for biological tissues visualization by fluorescence, light scattering, and nuclear magnetic resonance imaging.
