A simple and effective strategy on producing solution-processable materials with highly efficient persistent room-temperature-phosphorescence (RTP) is presented here.
Atomic-resolution image of a graphene sheet synthesized by remote plasma-enhanced atomic layer deposition at low temperatures.
Ultralong and colorful clusterization-triggered phosphorescence (CTP) has been realized by changing polymerization conditions of polyacrylamides (PAMs). These materials have huge potential in the application sensing, anti-counterfeiting LEDs.
Two-dimensional (2D) white-light-emitting hybrid perovskites (WHPs) are promising active materials for single-component diodes (WLEDs) driven by UV. However, the reported WHPs exhibit low quantum yields (≤9%) and color rendering index (CRI) values less than 85, which does not satisfy demand of solid-state lighting applications. In this work, we report a series mixed-halide 2D layered (C6H5C2H4NH3)2PbBrxCl4–x (0 < x 4) obtained from phenethylammonium cation. Unlike including...
Abstract Graphene/silicon Schottky junctions have been proven efficient for photodetection, but the existing high dark current seriously restricts applications such as weak signal detection. In this paper, a thin layer of gadolinium iron garnet (Gd 3 Fe 5 O 12 , GdIG) film is introduced to engineer interface graphene/silicon photodetector. The novel structure shows significant decrease in by 54 times at −2 V bias. It also exhibits performance self-powered mode terms an I light /I ratio up...
Abstract Photodetectors (PDs) play a crucial role in imaging, sensing, communication systems, etc. Graphene (Gr), leading two-dimensional material, has demonstrated significant potential for photodetection recent years. However, its relatively weak interaction with light poses challenges practical applications. The integration of silicon (Si) and perovskite quantum dots (PQDs) opened new avenues Gr the realm next-generation optoelectronics. This review provides comprehensive investigation...
Photoelectrochemical electrodes have been prepared by sequential deposition of quantum sized PbS, CdS and ZnS particles on TiO2 nanocrystalline films. Their photoelectrochemical properties studied in a two-electrode system which conforms more closely to practical conditions. The results show that the ternary sulfide PbS/CdS/ZnS co-sensitized electrode generates incident photon-to-current conversion efficiency (IPCE) as high nearly 100% under irradiation with 400 nm light; moreover its...

Organic afterglow materials (OAMs) with a lifetime longer than 0.1 s have recently received much attention for their fascinating properties meeting the critical requirements of applications in newly emerged technologies. However, development OAMs lags behind low luminescence efficiency. Usually, enhancing phosphorescence efficiency organic causes short lifetime. Here, we report two kinds OAMs, two-dimensional (2D) layered organic–inorganic hybrid zinc bromides (PEZB-NTA and PEZB-BPA),...

On this basis, new strategy generate white afterglow has been proposed by codoping short-wavelength long-wavelength phosphor organic–inorganic (OIHPs). As result, single-component...
Organic-inorganic hybrid metal halides have attracted intensive attention because of their unique electronic structure and solution processability. They a rigid micro/nano-structure heavy atom effect, which has obvious advantages in promoting organic room temperature phosphorescence (RTP). However, the toxicity metals limited further development. Herein, two metal-free 2D layered ammonium halides, homopiperonylammonium bromide chloride (HLB HLC), are described for first time. Their consists...
The flat band edges (Efb) of nanostructured SrTiO3 electrodes have been determined in propionitrile (PN), acetylacetone (Acac), and PN/Acac with spectroelectrochemistry measurements.

Abstract Herein we report on four diarylmaleimides based 3‐ or 2‐substituted benzothiophene (M3S M2S) and benzofuran (M3O M2O), which show very different emission properties: aggregation‐caused quenching (ACQ), aggregation‐induced (AIE), dual‐state strong (DSE) in both solution solid states. Their color the state can be adjusted from green–yellow into red. M2O displays red solid‐state at 630 nm with a quantum yield of 46.3 %. Single‐crystal X‐ray diffraction analysis confirms that their...
