Abstract An ideal anti-counterfeiting technique has to be inexpensive, mass-producible, nondestructive, unclonable and convenient for authentication. Although many technologies have been developed, very few of them fulfill all the above requirements. Here we report a non-destructive, inkjet-printable, artificial intelligence (AI)-decodable security label. The stochastic pinning points at three-phase contact line ink droplets is crucial successful inkjet printing labels. Upon solvent...
One of the great challenges in perovskite quantum dot light-emitting diodes (Pe-QLEDs) is unbalanced charge injection that significantly hinders device performance and stability. Herein, we tailor-made a high mobility electron-transporting material (ETM), named B2, to balance carrier blue Pe-QLEDs. B2 with tailored asymmetric anthracenyl structure exhibits promising electron 2.7 × 10–4 cm2·V–1·s–1, which almost 20 times higher than commonly used ETM-TPBi (1.1 10–5 cm2·V–1·s–1). Subsequently,...
Perovskite materials have exhibited promising potential for universal applications including backlighting, color conversion, and anticounterfeiting labels fabricated using solution processes. However, owing to the tendency of those uncontrollable morphologies form large crystals, they cannot be utilized in discontinuous microminiaturization, which is crucial practical optoelectronic applications. In this research, combining effects adding polyvinylpyrrolidone (PVP), precisely controlling...

Herein, we propose a facile strategy fabricate an super micro fingerprint (SMFP) array by introducing situ grown perovskite crystals for multilevel anticounterfeiting labels. The features are formed the basis differential transportation microscale precursor droplet during inkjet printing process, coupled with...
Abstract Quasi‐2D perovskites demonstrate exceptional luminescent properties, mainly attributed to heightened radiative recombination facilitated by the energy transfer process among spontaneous quantum‐well structures featuring varied n‐value distributions. However, rapid crystallization often induces uncontrolled variations in phase composition, characterized distinct “n” values, leading suboptimal efficiency. In this study, an innovative supramolecular strategy utilizing cryptand is...
Optical security labels play a significant role in protecting both our wealth and health. However, simultaneously meeting the requirements including low-cost fabrication, easy detection, high-level is still challenging for labels. Here, we design an unclonable anti-counterfeiting system with triple-level by using inkjet printing technique, which can be authenticated naked eyes, portable microscope, fluorescence microscope. These are achieved microscale quantum dot (QD) ink droplets on...

Improving the morphology and crystallinity of polycrystalline perovskite films is essential for solar cells (PSCs) with high efficiency stability. Herein, capsaicin‐based antisolvent additive engineering (AAE) proposed to fabricate MAPbI 3 ‐based p– i –n PSCs by simply adding capsaicin into simultaneously regulate crystallization passivate defects films. Meanwhile, a more n‐type surface formed spatially confined distribution at grain boundaries top interfaces induced AAE process, which...
The large volume expansion and self-locking phenomenon of metal hydride particles during hydrogen sorption often leads to a high stress concentration on the walls container, which may cause collapse container.

It...
Halide perovskites are emerging emitters with excellent optoelectronic properties. Contrary to the large grain fabrication goal in perovskite solar cells, light-emitting diodes (PeLEDs) based on small enable efficient radiative recombination because of relatively higher charge carrier densities due spatial confinement. However, achieving small-sized growth superior crystal quality and film morphology remains a challenge. In this work, we demonstrated nanostructured stamp thermal imprinting...
