Abstract Low‐dimensional Ruddlesden–Popper perovskites (RPPs) exhibit excellent stability in comparison with 3D perovskites; however, the relatively low power conversion efficiency (PCE) limits their future application. In this work, a new fluorine‐substituted phenylethlammonium (PEA) cation is developed as spacer to fabricate quasi‐2D (4FPEA) 2 (MA) 4 Pb 5 I 16 ( n = 5) perovskite solar cells. The champion device exhibits remarkable PCE of 17.3% J sc 19.00 mA cm −2 , V oc 1.16 V, and fill...
Lanthanide-doped fluoride nanoparticles (NPs) showcase adjustable X-ray-excited persistent luminescence (XEPL), holding significant promise for applications in three-dimensional (3D) imaging through the creation of flexible X-ray detectors. However, a dangerous high irradiation dose rate and complicated heating procedure are required to generate efficient XEPL high-resolution 3D imaging, which is attributed lack strategies significantly enhance intensity. Here we report that intensity series...
High-uniform nanowires with diameters down to 50 nm are directly taper-drawn from bulk glasses. Typical loss of these wires goes 0.1 dB/mm for single-mode operation. Favorable photonic properties such as high index tight optical confinement in tellurite glass and photoluminescence active devices doped fluoride phosphate observed. Supporting high-index solid substrates (such silica MgF2 crystal) assembling low-loss microcoupler also demonstrated. Photonic demonstrated this work may open up...

Electrochemical sensors have long suffered from issues such as nonspecific adsorption, poor anti-interference ability, and internal external disturbances. To address these challenges, we developed a facile electrochemical method, which integrated ratiometric strategy with self-cleaning electrodes. In the novel sensing system, electrode was realized via forming hydrophobic layer on carbonized ZIF-67@ZIF-8 (cZIF) by polydimethylsiloxane (PDMS) precursor vaporization. As for ratiometry, it is...
