White light emission of IFP-1 by in situ co-doping of the MOF pore system with Eu3+ and Tb3+

摘要: Co-doping of the MOF 3∞[Zn(2-methylimidazolate-4-amide-5-imidate)] (IFP-1 = Imidazolate Framework Potsdam-1) with luminescent Eu3+ and Tb3+ ions presents an approach to utilize porosity for intercalation luminescence centers tuning chromaticity emission white light quality a three color emitter. Organic based fluorescence processes backbone as well metal dopants are combined one homogenous single source emitter while retaining MOF's porosity. The lanthanide were doped in situ into IFP-1 upon formation by micropores growing framework without structure directing effect. Furthermore, point is temperature sensitive, so that cold higher blue content observed at 77 K warmer room (RT) due reduction organic temperatures. study further illustrates dependence amount on sorption properties proves pore system low-temperature site selective photoluminescence spectroscopy, SEM EDX. It also covers investigation border uptake within pores secondary phases formates surface MOF. Crossing from co-doping two-phase composite can be beneficially used adjust character warmth light. This describes two-color emitters formula Ln@IFP-1a–d (Ln: Eu, Tb) doping just or Tb3+.
