A new family of pyrimidine-based BF2 complexes () with aggregation-induced emission (AIE) and mechanochromic luminescence properties were developed. These compounds exhibit intense fluorescence in their aggregation/solid-state resulting from their large Stokes shift and AIE. X-ray crystallographic analysis shows that the weak intermolecular interactions by fixing the molecular conformations of ...
Enhancement of upconversion luminescence is imperative for the applications of upconversion nanocrystals (UCNs). In this work, we investigated the upconversion luminescence enhancement of NaYF4:Yb/Er by Mo(3+) ion doping. It was found that the upconversion luminescence intensities of the green and red emissions of UCNs co-doped with 10 mol% Mo(3+) ions were enhanced by 6 and 8 times, respective...
The new material consisting of Gd1.6Dy0.4(WO4)3 incorporated into silica xerogel was prepared via the coprecipitation method. The luminescence properties of the studied material were analyzed by means of emission and excitation spectra, including the result of luminescence lifetimes of Dy(III) ion. The enhanced yellow emission due to the excitation energy transfer from group to Dy(III) ion upon...
Two attractive detection strategies for bioassays are reviewed in this article. Both approaches use the highly sensitive time-resolved luminescence detection of lanthanide complexes in combination with a signal amplification scheme. While enzyme-amplified lanthanide luminescence (EALL) has been an established technique for more than a decade, nanoparticles doped with luminescent lanthanide comp...
