Near-Infrared (NIR) polymer light-emitting diode (PLED) based on organo-Yb3+-complex-grafted poly(N-vinylcarbazole) (PVK)

Based on [Zn(L1)(4-vinyl-Py)Yb(L2)3] (2)-grafted polymer Poly(NVK-co-2), Yb3+-centered NIR PLED with record-renewed performance (a maximum efficiency of 0.049%, a maximum irradiance of 78.68 μW/cm2), low turn-on voltage of 7 V and weak efficiency-roll-off is realized.273
