A homogeneous layer of Bi_2O_3-Bi_(14)WO_(24) composite(BWO/Bi_2O_3) thin film was fabricated using a combination of electrodeposition and thermal treatment. The evenly distributed Bi14 WO24 component within the Bi_2O_3 layer was found to be important in stabilising the photoelectrochemical performances of Bi_2O_3 photoanode by promoting the photoelectron transport. The unmodified Bi_2O_3 suffered from severe photocorrosion as proven by X-ray diffraction(XRD) and inductively coupled plasma(ICP) analyses while the composite thin film was active without noticeable activity decay for at least 3 h of illumination. This strategy might be applicable to other photocatalysts with stability issues.

Low-temperature fabrication of black-phase CsPbI3 perovskite films is first demonstrated by using diphenylphosphinic chloride additive under 30-50 degrees C, arising from the steric effect and chloride insertion ***-area high-quality all-inorganic perovskite films with fewer defects enhanced crystallographic orientation, and excellent environmental stability is *** record performances are demonstrated for flexible wearable photodetectors with a responsivity of 42.1 A W-1, a detectivity of 1.3 x 1014 Jones, high-fidelity image, photoplethysmography sensor functions, and high mechanical stability. Flexible wearable optoelectronic devices fabricated from organic-inorganic hybrid perovskites significantly accelerate the development of portable energy, biomedicine, and sensing fields, but their poor thermal stability hinders further applications. Conversely, all-inorganic perovskites possess excellent thermal stability, but black-phase all-inorganic perovskite film usually requires high-temperature annealing steps, which increases energy consumption and is not conducive to the fabrication of flexible wearable devices. In this work, an unprecedented low-temperature fabrication of stable black-phase CsPbI3 perovskite films is demonstrated by the in situ hydrolysis reaction of diphenylphosphinic chloride additive. The released diphenyl phosphate and chloride ions during the hydrolysis reaction significantly lower the phase transition temperature and effectively passivate the defects in the perovskite films, yielding high-performance photodetectors with a responsivity of 42.1 A W-1 and a detectivity of 1.3 x 1014 Jones. Furthermore, high-fidelity image and photoplethysmography sensors are demonstrated based on the fabricated flexible wearable photodetectors. This work provides a new perspective for the low-temperature fabrication of large-area all-inorganic perovskite flexible optoelectronic devices.

在当今的媒介化时代,随着互联网等新媒体技术对国家、社会不断的赋权与公共政治的崛起,公共交往在越来越便捷、普遍、常态化、多元的同时,也出现了一定的问题。其中,最为突出的问题是公共交往过程中组织机构与公民话语风格的偏误问题。鉴于此,文章立足于政治媒介化的时代背景,在公共政治视域下,借用话语理论,以我国公共政治交往话语实践的经验与教训为分析样本,以无责漫谈与话语独白为考察中心,探讨匡正当下公共政治交往话语风格偏误的方法与进路。研究认为,组织机构与公民应该积极、主动地进行话语转换,向彼此靠近,消减组织机构话语的话语独白与公民话语的无责漫谈,加速两者之间的话语循环与流通。具体举措包括:话语实践效果的想象与预测、话语的技术化处理、“中间人”的话语斡旋、话语的场域转化、话语的流通与循环、话语的破圈传播、话语的理性规制、话语中社会意见的冶炼、话语实践智慧的提炼等。

氧化锆具有声子能量低,介电常数高和带隙较宽等优良特性,并且立方相的氧化锆(cZrO_(2))透光率高,适合作为上转换发光材料的基质.采用基于密度泛函理论(DFT)的第一性原理平面波赝势法研究了稀土元素Er、Yb和Y掺杂cZrO_(2)的电子结构和光学性质.计算结果显示,掺入Y元素后,cZrO_(2)转变为直接带隙材料,继续掺入Er和Yb原子后,费米能级移动到价带内,带隙显著减小.Y和Er混掺后,增强了cZrO_(2)在近红外波段的吸收能力.继续掺入Yb后,cZrO_(2)对近红外波段的吸收能力有了进一步地增加.
