The ever growing interest in rare earth coordination compounds and materials wilh optical properties stems from applications in multidisciplinar fields such as nanosensors, materials for telecommunications. lighting devices, and luminescent probes for bioanalyses and live cell imaging and sensing. Most of these applications use the unique ability of lhe rare earth ions to emit well-defined narrow bands in different spectral ranges, from visible to near-infrared. Due to the low absorption cross-section of the f.f transitions, efficient population of lhe excited 4f states has to rely on energy transfer from the surroundings of Ihe metal ion (antena effect or luminescence sensitization). Another point desirable is the use of RE3+ ions wilh emission in the near-infrared (NIR) region reducing !he interference from biological materials in the analyses. In this work. we report the preparation and characterization of rare earth coordination compounds and nanoparticles based on rare earth ions. RE3+ beta-diketonate complexes with macrocyclic ligand has been synthesized and characterized and are being used to mark hemoglobin S (sickle cells) Leishmania (tropical disease) and PSA (Prostate-specific antigen that is a protein produced by cells of the prostate gland. The PSA test measures the level of PSA in the blood). Several nanoparticles based on Nd3+, Eu3+ and Tb3+ ions doped into the Y2O3 matrix. are also being synthesized and evaluated for labeling anti-oxLDL (anti-oxidized low density lipoproteins), one of the principal causes of cardiovascular diseases and responsible for around 30% of deaths world-wide. information about struture and average grain size of these nanoparticles were obtained by x-ray diffration (XRDJ, transmission electron micrograph (TEM) and infrared absorption spectroscopy.
