Enhanced 1.54 μm PL and EL on a perfluorinated Er3+ complex sensitized by an Ir3+ complex

Caption

(Left) The emission intensity per percentage Er3+ at 1532 nm as a function of laser power density for Ir-tBuPBI co-doped film with different molecular concentrations of Er(F-TPIP)3. The solid line represents 405-nm excitation, and the dashed line represents 655-nm excitation. (Right) The EL spectra of OLEDs with different molecular ratios of Ir-tBuPBI:Er(F-TPIP)3 driven with 14 V. 5% Er(F-TPIP)3+95% Ir-tBuPBI (A), 10% Er(F-TPIP)3+90% Ir-tBuPBI (B), 30% Er(F-TPIP)3+70% Ir-tBuPBI (C), 50% Er(F-TPIP)3+50% Ir-tBuPBI (D), 100% Ir-tBuPBI (E) and 10% Er(F-TPIP)3+90% AlQ3 (F).
