Article Synopsis
- Two-dimensional perovskites with organic fluorophores can serve as effective emitters for LEDs, though previous designs had low external quantum efficiencies (EQEs).
- This study increased EQE to about 10% by selecting a fluorophore that complements the energy levels of the perovskite structure, improving exciton formation and avoiding energy losses.
- Enhanced light-outcoupling efficiency due to light scattering in the polycrystalline perovskite layer also contributes to effective electroluminescence, paving the way for high-performance, low-cost LED products.
A very high hole mobility of 15 cm V s along with negligible hysteresis are demonstrated in transistors with an organic-inorganic perovskite semiconductor. This high mobility results from the well-developed perovskite crystallites, improved conversion to perovskite, reduced hole trap density, and improved hole injection by employing a top-contact/top-gate structure with surface treatment and MoO hole-injection layers.
