Luminescent nanomaterials doped with lanthanide ions have attracted considerable attention and due to their unique properties allow for applications in various areas, e.g. optoelectronics, display panels, solar cells, sensors. This lecture presents selected nanomaterials based on inorganic matrices (e.g.: fluorides, vanadates, borates, etc.) doped with luminescent lanthanide (Ln) ions, characterized by efficient emission properties. As application materials, they show: phase purity, high crystallinity and homogeneity, small particle size and narrow particle size distribution, and should not be agglomerated. Examples of effective nanoluminophores (NL) and up-converting (UCNL) doped with Ln3+ (or Ln2+) ions and their surface functionalized, by coting with organic compounds, hybrid systems for sensing and analytical applications are discussed in detail. Nanoparticles (NPs) functionalized with organic compounds have proven to be very useful for analytical and biomedical and purposes. We have developed new highly sensitive and highly selective fluorescence methods [1-2] based on energy transfer from the analyte ion to the Tb3+ ion, or Eu3+ ion NPs for the (sensing) determination of metal species (e.g. Cu2+, Al3+) in real water samples. The presentation shows and discusses examples of effective luminescent nanoparticles doped with Ln3+ (Tb3+ or Eu3+) ions in systems functionalized with the desired organic ligand molecules, e.g.: LaF3: Tb3+, Ce3+ @SiO2-NH2 nanoparticles with acetylsalicylic acid (aspirin) coated on the surface [3], or ligand sensitized: 2,6-Pyridine dicarboxylic acid capped-LaF3:Eu3+ and adenosine capped-SrF2:Eu3+ nanoparticles (NPs) [3], showed high hemocompatibility and therefore can be successfully used in biomedical research. In this lecture also present examples of selected Ln-doped NLs or UCNLs that can be successfully used as optical sensors, capable of measuring temperature and/or pressure for (nano)-thermometry or/and (nano)-manometry [4].
