Electro-photoluminescence in organics
PublicationElektro-fotoluminescencję zaobserwowano w układzie ITO(+)/emiter/Ca(-), gdzie emiter wzbudzany światłem UV (350nm) zawierał dendrymer aminowy m-MTDATA, pochodną fenantroliny BPT i organiczny kompleks platyny PtL2Cl. Widmo fotoluminescencji pochodzi od singletowych ekscypleksów m-MTDATA:BPT i trypletowych ekscypleksów m-MTDATA:PtL2Cl. Ze wzrostem pola elektrycznego następuje wygaszanie ekscypleksów na skutek ich dysocjacji na nośniki...

A Family of Pb-based Superconductors with Variable Cubic to Hexagonal Packing
PublicationWe describe three previously unreported superconductors, BaPb3, Ba0.89Sr0.11Pb3, and Ba0.5Sr0.5Pb3. These three materials, together with SrPb3, form a distinctive isoelectronic family of intermetallic superconductors based on the stacking of Pb planes, with crystal structures that display a hexagonal to cubic perovskite-like progression, as rarely seen in metals. The superconducting transition temperatures (Tc) are similar for...
