Conventional optical anti-counterfeiting strategies are based on the single-color emission, which easily deciphered and thus greatly limited in application of information security. Herein, a multimodal dynamic coding with red, green, blue (RGB) tricolors has been developed by photoluminescence (PL), persistent luminescence (PersL), thermally stimulated (TSL), (TSPL). The BaSi2O2N2:Eu2+ phosphors emission peak at 494 nm were used as crucial material exhibited distinctive response properties...
Abstract The combination of p‐type NiO x and self‐assembled monolayers (SAMs) has recently emerged as an optimal structure for hole transport layer (HTL) in wide‐bandgap perovskite solar cells (WBG PSCs). However, the unique requirements this cascade HTL system differ significantly from those neat . Specifically, tendency to agglomerate can lead poor film morphology inadequate interfacial contact with SAMs, resulting significant open‐circuit voltage ( V oc ) loss PSCs. Herein, these issues...
Abstract Formamidinium (FA)‐based Sn‐Pb perovskite demonstrates superior thermal stability, making it well‐suited for all‐perovskite tandem solar cells. However, the uncontrolled crystallization process remains a significant challenge. In this study, an effective strategy is presented to regulate of FA‐based by incorporating perfluoroanionic surfactant (perfluorohexanesulfonic acid potassium salt, F 13 C 6 SO 3 K) into precursor. The multifunctional sites K, including atoms and − groups,...
Abstract Reducing defect density is of significant importance for enhancing the power conversion efficiency (PCE) and stability perovskite solar cells (PSCs). While most previous outstanding studies have focused on individual layers within device structure. Herein, a three‐in‐one strategy using aminoacetonitrile hydrochloride (AmiHCl) molecule to reduce defects in bulk surface perovskite. The results study found that AmiHCl bottom modification can decrease number buried interface holes,...
Abstract Although p‐i‐n type inverted perovskite solar cells (PSCs) achieve excellent photoelectric efficiencies, the nonradiative recombination at perovskite/C 60 interface is still key factor affecting overall efficiency of PSCs. Herein, a synergistic passivation strategy (meta‐fluoro‐phenylethylammonium iodide and piperazine iodide) developed to modify in This facilitates situ reconstruction film obtain smooth flat surface. Furthermore, two molecules work synergistically passivate surface...
Advanced fluorescent anticounterfeiting technology has received widespread attention due to the lack of sufficient security traditional anti-counterfeiting. Hence, there is a great challenge continuously develop multi-level anti-counterfeiting with higher security. Here, we desired based on CsPbBr3 perovskite quantum dots (PQDs) and CaAl2O4:Eu2+, Nd3+ composites persistent luminescence properties. PQDs can be formed surface CaAl2O4 host exhibit an average diameter around 3.5 nm. The...
Abstract The commonly used hole transport layer (HTL) Poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) still has some shortcomings that will limit the development of Pb–Sn perovskite solar cells (PSCs). In this work, multifunctional ammonium sulfide (AS) is attempted to modify PEDOT:PSS/perovskite interface. AS multiple effects on different functional layers and device as a whole: a) optimize crystallization by formation PbS nucleation sites; b) neutralize acidity...
Abstract The non‐wetting issue of the self‐assembled monolayer (SAM) layer can complicate subsequent perovskite deposition and impact device efficiency. This study addresses this challenge using a dual approach involving co‐self‐assembly buffer to enhance wettability interfacial contact buried film. A weakly acidic boronic acid derivative, 4‐N, N‐dimethylbenzeneboronic hydrochloride (4NPBA), is used co‐self‐assemble with regular SAM molecule on ITO FAI further increased film coverage 89%....
Nowadays, considerable efforts have been extensively devoted to explore a general strategy for improving the color uniformity and thermal stability of phosphors, which is vital its applications in health comfort lighting.

As an all-inorganic solid state lighting material, phosphor-in-glass (PiG) receives much attention in high-power white lighting. However, poor heat-dissipation performance and low color rendering index (Ra) caused by doping concentration of phosphor limit its application laser diodes (wLDs). Herein, films on sapphire (PiFS) with heat-conducting properties high Ra were newly synthesized via screen printing technology, which is highly desired for wLEDs/wLDs. The interfacial corrosion product...
