The strong ionic character endows all‐inorganic CsPbX 3 (X = Cl, Br, I) perovskite nanocrystals (NCs) with different chemical features from classical Cd‐based NCs, especially when considering their interaction polar solvents and surfactants. This has aroused intensive interest, but is still short of comprehensive understanding. More significantly, above characteristic may be used to improve the quality thin films, which crucial for carrier transport inside optoelectronic devices. Here, an...

Intrinsically high mobility and large absorption coefficient endow inorganic halide perovskites (IHPs) with great promise for high-performance photodetectors (PDs), which, however, are being hindered by the low carrier extraction transport efficiency of solution assembled films. Here, we report on a general strategy to enhance perovskite film conductivity that carbon nanotubes (CNTs) conductive nanonets constructed from provide fast tracks. Resultantly, CsPbBr3 nanosheet/CNT composite films...

Halide perovskite (HP) nanocrystals (NCs) have recently shown great potential for X-ray detection and imaging. However, the practical application still has a long way to go with many technical requirements waiting be fulfilled, including structure optimization, stability enhancement, cost reduction. A design principle in this beginning stage is urgently needed but lacking. Herein, an "emitter-in-matrix" refined from commercial scintillators, CsPbBr3@Cs4PbBr6 emissive CsPbBr3 NCs embedded...

Transition metal dichalcogenides (TMDs) are promising candidates for flexible optoelectronic devices because of their special structures and excellent properties, but the low optical absorption ultrathin layers greatly limits generation photocarriers restricts performance. Here, we integrate all-inorganic perovskite CsPbBr3 nanosheets with MoS2 atomic take advantage large coefficient high quantum efficiency perovskites, to achieve performance TMD-based photodetectors. Significantly,...

Abstract Ensuring nuclear safety has become of great significance as power is playing an increasingly important role in supplying worldwide electricity. β-ray monitoring a crucial method, but commercial organic scintillators for detection suffer from high temperature failure and irradiation damage. Here, we report type scintillator with good thermotolerance hardness based on two-dimensional halide perovskite. Comprehensive composition engineering doping are carried out the rationale...

With regards to developing miniaturized coherent light sources, the temperature‐insensitivity in gain spectrum and threshold is highly desirable. Quantum dots (QDs) are predicted possess a temperature‐insensitive by virtue of separated electronic states; however, it never observed colloidal QDs due poor thermal stability. Besides, for classical II–VI QDs, profile generally redshifts with increasing temperature, plaguing device chromaticity. Herein, this paper addresses above two issues...

Abstract Delicate engineering of chromaticity is required to faithfully reproduce colors in a backlit display, this extremely difficult for green downconverters because the human eye highly sensitive colors. The central challenge achieve finely tunable emissions narrow range 525–535 nm while keeping full width at half maximum (FWHM) <25 same time.

Fluorescence imaging with photodetectors (PDs) toward near-infrared I (NIR-I) photons (700-900 nm), the so-called "optical window" in organisms, has provided an important path for tracing biological processes vivo. With both excitation and fluorescence this narrow range, a stringent requirement arises that signal should be efficiently differentiated effective sensing, which cannot fulfilled by common PDs broadband response such as Si-based PDs. In work, delicate optical microcavities are...
