Abstract Mobile and wearable devices are increasingly reliant on near-infrared (NIR) covert illumination for facial recognition, eye-tracking or motion depth sensing functions. However, these small offer limited spatial real estate that is typically already occupied by their full-area electronic color displays. Here, we report a transparent perovskite light-emitting diode (LED) could be overlaid across display to provide an efficient high-intensity NIR illumination. Our constructed with...

Abstract Metal halide perovskite quantum dots (PQDs) have emerged as promising materials due to their exceptional photoluminescence (PL) properties. A wide range of applications could benefit from adjustable luminescence properties, while preserving the physical and chemical properties PQDs. Therefore, post‐synthesis engineering has gained attention recently, involving use ion‐exchange or external stimuli, such extreme pressure, magnetic electric fields. Nevertheless, these methods typically...

Solution-processed organic light-emitting diodes (s-OLED) consisting of TAPC/TmPyPB interfacial exciplex host and polymer PAPTC TADF emitter are prepared, simultaneously displaying ultralow voltages (2.50/2.91/3.51/4.91 V at luminance 1/100/1000/1000 cd m-2), high efficiencies (14.9%, 50.1 lm W-1), extremely low roll-off rates (J50 63.16 mA cm-2, L50 ca. 15000 m-2). Such performance is distinctly higher than that pure-PAPTC s-OLED. Compared to pure-PAPTC, the advanced emissive layer...

Abstract Near‐infrared (NIR) lighting plays an increasingly important role in new facial recognition technologies and eye‐tracking devices, where covert nonvisible illumination is needed. In particular, mobile or wearable gadgets that employ these require electronic components with ultrathin flexible form factors are currently unfulfilled by conventional GaAs‐based diodes. Colloidal quantum dots (QDs) emerging perovskite light‐emitting diodes (LEDs) may fill this gap, but generally...

Organometal halide perovskites (OHPs) are becoming a hot topic in the field of display and lighting. Unlike strategy used for solar cells, that is, using several hundred nanometers thick OHP film fully absorbing light to convert electricity, thin-film OHPs (<50 nm) advantageous restrain its self-absorption drawback thus beneficial preparing efficient light-emitting diodes (LEDs). Here we manipulate excess molar ratio MABr/PbBr2 precursors post-annealing temperature obtain uniform suppress...

Field effect transistor (FET) has attracted high attention in biomolecules detection. However, the sensitivity of FET-based biosensors is often limited by charge screening effect. In addition, facile and ultra-sensitive detection for small biomolecules, which possess weak or electroneutral, remains to be studied. Here, self-assembled monolayer AuNPs/three-dimensional (3D) crumpled graphene FET structured a biosensor shrinking flexible polystyrene (PS) films through heat treatment method...
