In this work we present experimental evidence that the valence instability of the ytterbium ion play a key role for the observed photodarkening mechanism in Yb-doped fiber lasers. Luminescence and excitation spectroscopy performed on UV irradiated Yb/Al doped silica glass

Based on a donor-acceptor framework, several conjugates have been designed and prepared in which an electron-donor moiety, ytterbium(III) porphyrinate (YbPor), was linked through an ethynyl bridge to an electron-acceptor moiety, boron dipyrromethene (BODIPY). Photoluminescence studies demonstrated efficient energy transfer from

A novel CT contrast agent denoted as BaYbF(5) @SiO(2) @PEG is presented. The as-prepared nanoparticles exhibit significantly enhanced contrast efficacy relative to clinical iodinated agents and maintain higher X-ray attenuation at different voltages, suitable for diagnostic imaging of various patients.
