Abstract The slow bimolecular recombination that drives three-dimensional lead-halide perovskites’ outstanding photovoltaic performance is conversely a fundamental limitation for electroluminescence. Under electroluminescence working conditions with typical charge densities lower than 10 15 cm −3 , defect-states trapping in perovskites competes effectively the radiative recombination. Herein, we overcome this using van-der-Waals-coupled Ruddlesden-Popper perovskite multi-quantum-wells....
The metaverse has gained popularity recently in many areas including social media, healthcare, education and manufacturing. This work explores the use of concept for cultural heritage applications. motivation is to develop a systematic approach construction offer, potentially, more effective solutions tourism guidance, site maintenance, object conservation, etc. We propose framework this with an emphasis on fundamental elements characterization mapping between physical virtual worlds....
Abstract Halide substitution in phenethylammonium spacer cations (X‐PEA + , X = F, Cl, Br) is a facile strategy to improve the performance of PEA based perovskite solar cells (PSCs). However, power conversion efficiency (PCE) X‐PEA quasi‐2D (Q‐2D) PSCs still unsatisfactory and underlying mechanisms are debate. Here, in‐depth study on impact halide crystal orientation multi‐phase distribution films reported. The eliminates n 1 2D thus leads perpendicular orientation. Furthermore, nucleation...
Abstract Lead halide perovskites are considered as very promising photovoltaic materials due to their tunable direct bandgaps, large absorption coefficients, long carrier diffusion lengths, and ultralow trap state densities, etc. With these unique properties, the lead have also demonstrated great potential for use semiconductor gain materials. In this review, a snapshot on recent advances of perovskite micro‐ nanolasers is given. The dependence lasing performance dimensionality, crystal...

Formamidinium lead triiodide (α-FAPbI3 ) has been widely used in high-efficiency perovskite solar cells due to its small band gap and excellent charge-transport properties. Recently, some additives show facet selectivity generate a (001) facet-dominant film during crystallization. However, the mechanism realize such is not fully understood. Here, authors attempted use three ammonia salts NH4 X (X are pseudohalide anions) achieve better crystallization improved crystallinity. After addition,...
The modification of perovskite precursor by a series phosphoryl chloride molecules can indeed improve the performance LEDs (Pero-LEDs). bis(2-oxo-3-oxazolidinyl) phosphinic not only regulate phase distribution controlling crystallization rate but also passivate defects quasi-2D perovskite. Highly efficient and reproducible Pero-LEDs are achieved with an maximum external quantum efficiency (EQEmax) 20.82% average EQE (EQEave) around 20% on 50 devices. Quasi-2D perovskites have attracted...
Abstract Multiple ultrashort laser pulses are widely used in optical spectroscopy, optoelectronic manipulation, imaging and signal processing etc. The pulse multiplication, so far, is solely realized by using the setups or devices to modify output from gain medium. employment of these external techniques because medium itself incapable modifying multiplying generated pulse. Herein, with single femtosecond excitation, we achieve double-pulsed stimulated emission duration around 40 ps interval...
Solution processed organic-inorganic hybrid perovskites are emerging as a new generation materials for optoelectronics. However, the electroluminescence is highly limited in light emitting diodes (LED) due to low exciton binding energy and great challenge stability. Here, we demonstrate super air stable quasi-two dimensional perovskite film employing hydrophobic fluorine-containing organics barrier layers, which can store ambient more than 4 months with no change. The dramatically reduced...
