Inorganic CsPbX3 (X = Cl, Br, I, or hybrid among them) perovskite quantum dots (IPQDs) are promising building blocks for exploring high performance optoelectronic applications. In this work, the authors report a new structure that marries IPQDs to silicon nanowires (SiNWs) radial junction structures achieve ultrafast and highly sensitive ultraviolet (UV) detection in solar-blind spectrum. A compact uniform deployment of upon sidewall low-reflective 3D junctions enables strong light field...
Perovskite structured CsPbX 3 (X = Cl, Br or I) quantum dots (QDs) have attracted great attention in the past few years for appealing application potentials photovoltaic and optoelectronic devices. In this report, QDs are shown to perform as a new probe metal ions with high sensitivity, selectivity instant response by quenching enhancing of photoluminescence (PL). Through experimental calculation efforts, probing mechanisms investigated. A wide window Cu 2+ Yb 3+ ranging from 2 × 10 −9 −6 m...

Abstract Low dimensional semiconductor nanomaterials have shown their tailorable properties for a variety of promising applications in decades. Here general strategy to synthesize all‐inorganic CsPbX 3 (X = Cl, Br, I or mixture) perovskite 2D nanoplates by introducing additional metal halides MX' 2 (M Cu, Zn, Al Pb, etc.; X' Br I) is reported. These uniform thickness and tunable size, which can be feasibly controlled the component ratio halides, temperature, time, ligands. The well‐defined...
Abstract Light‐emitting diodes based on perovskite quantum dots have attracted much attention since they can be applied in low‐cost display, biosensors, and other optoelectronic devices. Here, all‐inorganic light‐emitting n‐type dots/p‐Si heterojunction are fabricated. Both the green red light emission achieved at room temperature. The output power density is 0.14 mW cm −2 for device 0.25 one. relatively low turn voltage high intensity attributed to small hole injection barrier between CsPbI...
Abstract Combining inorganic perovskite quantum dots (IPQDs) devices with Si platform is an interesting topic since it helpful for realizing the optoelectronic integration as well multiple‐functional electronics in a compact and lightweight format. However, poor energy band alignment between IPQDs limits device performance, such emitting efficiency. Here, light‐emitting diodes (LEDs) structure proposed by inserting poly‐TPD (poly[ N , ′‐bis(4‐butylphenyl)‐ ′‐bis(phenyl)‐benzidine]) layer...
Antimony sulfoiodide (SbSI) is commonly known as a prototypical ferroelectric semiconductor. We report herein top-down strategy of ball-milling followed by size selective centrifugation to prepare SbSI nanocrystals (NCs). Taking the well dispersed NCs average 80 nm photocatalyst, record high visible light efficiency in photodegradation methyl orange (MO) water was achieved. By using 300 W xenon lamp with 420 cutoff filter and 1 g/L, MO solution 30 mg/L can be degraded ∼99% 10 s. The...

Graphene is an attractive optoelectronic material for various devices, especially in the field of photoelectric detection due to its high carrier mobility and fast response time. However, relatively low light absorption cross-section electron-hole recombination rate can lead rapid exciton annihilation small gain, which restrict commercial applications pure graphene-based photodetector.
