The instability of lead halide perovskites (LHPs) has tremendously hindered their practical applications. Although some examples on encapsulating LHPs into a SiO2 shell have been reported, these SiO2-coated still suffer from limited stability. Herein, MAPbBr3 (MA = CH3NH3+) nanoparticles encapsulated in double hydrophobic shells organic functionalized and poly(vinylidene fluoride) (MAPbBr3@SiO2/PVDF) are successfully synthesized by infiltrating the precursor solution hollow siliceous...
The design of photoluminescence-quenching probes for molecular oxygen (O2) is always a large space to explore. Luminescent semiconductor nanocrystals (NCs) have been proposed as emerging oxygen-responsive probes, but the inherent O2 sensing phosphorescent NCs has not reported so far. Here, we demonstrate capability MnII-doped CsPbCl3 (Mn:CsPbCl3 NCs) and reveal role on optical de-excitation process such perovskite (PNCs). By adjusting amount distribution MnII dopants, well host-dopant energy...
A shipborne detection device has been developed for the of heavy metal ions in offshore seawater, utilizing a mercury film electrode. The automatic determination Cd2⁺ and Pb2⁺ seawater can be conducted without any manual intervention. Waste solutions are collected recycling bag subsequent treatment, thereby preventing environmental pollution. accuracy, as well stability measurements, were thoroughly examined. relative standard deviation was determined to 7.02% after conducting 10 repeated...
Abstract Temperature sensing based on fluorescent semiconductor nanocrystals has recently received immense attention. Enhancing the trap‐facilitated thermal quenching of fluorescence should be an effective approach to achieve high sensitivity for temperature sensing. Compared with conventional nanocrystals, defect‐tolerant feature lead halide perovskite (LHP NCs) endows them density defects. Here, hollow mesoporous silica ( h ‐SiO 2 ) template‐assisted ligand‐free synthesis and halogen...
In this study, a three-phase heterostructure interface including glassy carbon (conducting medium), CsPbBr3 perovskite nanocrystals (PNCs, emitter) and acetonitrile (electrolyte) is constructed for fully investigating the interfacial electrochemiluminescence (ECL) behavior of PNCs. We find that these interfaces serve as bridges efficient electron-hole transfer during ECL process. As proof concept, increase area will accordingly enhance intensity About seven-fold enhancement could be achieved...
Abstract Lead ( Pb 2+ ), due to its non‐biodegradable property and biological accumulation, would have adverse effects on human body. In this study, a poly(pyrrole thiourea) modified electrode was developed using the electropolymerization of pyrrole thiourea. Compared with drop‐casting method, immobilization material fixator modification efficiency an improved. The applied for in‐situ determination in water coupled electrochemical flow analysis device. Several experimental parameters were...
Low-dimensional (LD) organic-metal halides (OMHs) have been extensively investigated because of their excellent optical properties. However, the rational synthetic control (dimension regulation) LD-OMHs has not yet established well. The effect organic cations on luminescence also remains unexplored. Here, we designed a double-chain ammonium salt 1 with two amine functional groups. Using hydrogen bonding between −N–H3 protons and halogen ions synthesized zero-dimensional (0D) OMH...
