TLDR
This critical review describes the latest developments in the sensitization of near-infrared luminescence, "soft" luminescent materials (liquid crystals, ionic liquids, ionogels), electroluminescentmaterials for organic light emitting diodes, with emphasis on white light generation, and applications in luminecent bio-sensing and bio-imaging based on time-resolved detection and multiphoton excitation.Abstract:
Recent startling interest for lanthanide luminescence is stimulated by the continuously expanding need for luminescent materials meeting the stringent requirements of telecommunication, lighting, electroluminescent devices, (bio-)analytical sensors and bio-imaging set-ups. This critical review describes the latest developments in (i) the sensitization of near-infrared luminescence, (ii) “soft” luminescent materials (liquid crystals, ionic liquids, ionogels), (iii) electroluminescent materials for organic light emitting diodes, with emphasis on white light generation, and (iv) applications in luminescent bio-sensing and bio-imaging based on time-resolved detection and multiphoton excitation (500 references).read more

Sol–gel preparation and photoluminescence properties of tetragonal ZrO2:Y3+, Eu3+ nanophosphors
TL;DR: By controlling Eu3+ doping concentration, ZrO2:Y3+, Eu 3+ (YSZ:Eu) nanophosphors with tetragonal structure have been prepared by sol-gel method and properties of the resulting phosphors are characterized by X-ray diffraction, transmission electron microscope (TEM), photoluminescence (PL) spectra and decay curve as mentioned in this paper.

Highly luminescent colloidal Eu(3)+-doped KZnF(3) nanoparticles for the selective and sensitive detection of Cu(II) ions.
TL;DR: A green synthetic approach to prepare water dispersible perovskite-type Eu3+-doped KZnF3 nanoparticles using environmentally friendly microwave irradiation at low temperature (85 8C) with water as a solvent, which could be used as a tool for bioimaging.

TL;DR: Ligands containing the [2,6-bis(1,2,3-triazol-4-yl)pyridine] (btp) motif have recently shown promise in coordination chemistry and were studied by means of probing their photophysical properties in organic solutions using lanthanide ion titrations.

Fine Tuning of Multicolored Photoluminescence in Crystalline Magnetic Materials Constructed of Trimetallic EuxTb1–x[Co(CN)6] Cyanido-Bridged Chains
TL;DR: A synthetic methodology in which both luminescent and magnetic functionalities are induced within lanthanide-based coordination polymers by the application of hexacyanocobaltate(III) anions and 3-hydroxypyridine (3-OHpy), both coordinated to 4f-metal ions modulating the lanthanid-centered properties is presented.

Two-Photon Laser Scanning Fluorescence Microscopy
TL;DR: The fluorescence emission increased quadratically with the excitation intensity so that fluorescence and photo-bleaching were confined to the vicinity of the focal plane as expected for cooperative two-photon excitation.

Upconversion and Anti-Stokes Processes with f and d Ions in Solids
TL;DR: Before the 1960s, all anti-Stokes emissions, which were known to exist, involved emission energies in excess of excitation energies by only a few kT and were linked to thermal population of energy states above excitation states by such an energy amount.
