This paper reported on a system for the detection of trace acetylene (C2H2) gas utilizing surface mounted device quartz tuning fork (SMD QTF) in conjunction with light-induced thermoelastic spectroscopy (LITES) and provided comparative analysis against conventional plug-in (P-QTF). The SMD QTF is cost-effective standard instrument featuring transparent glass shell smaller size, which eliminates need stripping LITES effectively mitigates oxidation as well drift resonance frequency. has almost...
Abstract Inspired by the structural feature of classical hole‐transport material (HTM), Spiro‐OMeTAD, many analogues based on a highly symmetrical spiro‐core were reported for perovskite solar cells (PSCs). However, these HTMs prone to crystallize because high molecular symmetry, forming non‐uniform films, unfavorable device stability and large‐area processing. By lowering symmetry spiro‐core, we report herein novel spirobisindane‐based HTM, Spiro‐I, which could form amorphous films with...
Active engineering and modulation of optical spectra in a remote fully reversible light is urgently desired photonics, chemistry, materials. However, the real-time regulation multiple information such as wavelength, bandwidth, reflectance, polarization still longstanding issue due to lack an appropriate photoresponsive candidate. Herein, we propose additional "degree-of-freedom (DOF)" photo-modulated soft helix, build up unprecedented inhomogeneous helical pitch length with...
Two –OH-based organic semiconductors with long-wavelength absorption and a high LUMO were developed as acceptors in bulk heterojunctions for solar cells (a PCE of 16.71%) photocatalytic hydrogen evolution (an EQE 9.17% at 800 nm).
We report the demonstration of continue wave operation diode end-pumped Er:Y2O3 and Er:Lu2O3 ceramic lasers operating at 2.7 μm room temperature. The maximum output power 320 mW 611 was obtained from lasers, with slope efficiency 6.5% 7.6%, respectively. Characteristics Red-shift in lasing wavelength investigated discussed. study indicates that under 967 nm 976 LD pumping, 15 at.% Er-doped Lu2O3 exhibit a better performance than Y2O3
Abstract Vortex beams carrying orbital angular momentum have important applications in high dimensional optical information processing, manipulations of tiny particles, super-resolution imaging and so on. Among various components, metasurface represents an ideal platform for realizing vortex with multiple functionalities due to its strong ability manipulating the phase, polarization amplitude light.

Abstract As one type of recent emerging lead‐free perovskites, Cs 2 ZrCl 6 nanocrystals are widely concerned, benefiting from the eminent designability, high X‐ray cutoff efficiency, and favorable stability. Improving luminescence performance has great importance to cater for practical applications. In view surface defects frequently formed by liquid phase method, particle morphology quality this material expected be regulated if certain intervention is made in synthesis process. work,...
The triangle refractive index profile of LEAF fiber (a non-zero dispersion shifted fiber) makes it much more sensitive to temperature and strain. Owing its high stimulated Brillouin scattering (SBS) threshold for long distance distributed sensors, we studied the spectrum characteristics under different strain conditions. results are compared with those SMF-28. Based on linear relationship between four peaks' linewidth/peak frequency strain/temperature, achieved a error 37 με 1.8 <sup...
Methoxydiphenylamine-substituted carbazole (MODPACz) is widely used to construct hole-transporting materials (HTMs) for perovskite solar cells (PSCs), whose performances rely highly on the linking way of MODPACz units and simplicity π-bridge. In this paper, we report a new HTM, pPh-2MODPACz, using one simplest π-bridges p-phenylene link units. The structural feature endows pPh-2MODPACz with high hole mobility conductivity, efficient extraction ability, good film-forming property....
In linear optics, the metasurface represents an ideal platform for encoding optical information because of its unprecedented abilities manipulating intensity, polarization, and phase light wave with subwavelength meta-atoms. However, controlling various degrees freedom in nonlinear optics remains elusive. Here, we propose a plasmonic working near-infrared regime that can simultaneously encode images real Fourier spaces. This is achieved by designing diatomic meta-molecule, which enables...
Abstract Bottom‐surface defect passivation of perovskite film, lagging far behind easily conducted bulk and top‐surface passivations in solar cells (PSCs), remains rather challenging because most molecules/groups can be eroded by polar solvents used for the subsequent deposition. In this work, an effective bottom‐surface is enabled enhanced performance inverted PSCs covalently attaching a group (hydroxyl) to hole transporting polymer. A short linker (methylene) between hydroxyl conjugated...
Abstract Flexible circularly polarized luminescence (CPL) exhibits significant potential for applications in smart wearable devices and high‐end anti‐counterfeiting. However, existing technologies suffer from low dissymmetry factor ( g lum ) poor mechanical reliability. Here, a metal halide perovskite is employed as the emitter to construct efficient robust flexible CPL films through facile strategy of bilayer stacking, which comprises layer nanocrystalline embedded polymer film photonic...
Abstract Luminescent materials with engineered optical properties have been developed for multiplexed labeling detection, where encoding capacity plays a pivotal role in the efficiency. However, multi‐dimensional identities are usually not independent which essentially hinder practical numbers to access theoretical capacity. In this work, we carefully studied sensitizer gradient doping structure near‐infrared (NIR) excitable upconversion nanoparticles (UCNPs) and managed achieve emission...
