Lead halide perovskite nanocrystals (NCs) are promising optical materials in many fields. However, their poor moisture stability, significant toxicity, and difficulty to be further functionalized greatly hinder applications bioimaging. Here, a universal strategy is demonstrated by simply encapsulating CsPbX3 (X = Cl, Br, I) NCs into phospholipids achieve CsPbX3-phospholipid micelles (CsPbX3@phospholipid) as probes for multiplex encoding cellular imaging or tumor-targeted imaging. The layer...

In this work, Cs2TeCl6 was synthesized by mechanochemistry its structure characterized using X-ray diffraction, the aligning of experimental computational results demonstrate reliability geometrically optimized crystal. First principles calculation conducted to analyze evolutions...
The first reported CsPbBr<sub>3</sub> perovskite ring array with tunable sizes from 2.6 μm to 16.9 was fabricated by using a 2D polystyrene colloidal crystal template and is expected be used in the fields of display lasers.
In the past few decades, trap emission was always believed hardly manipulated to luminescent quantum dots (QDs). Actually, not all emissions are useless. This work shows that interface between MnSe dopant and ZnSe host could be used for manipulating irradiative defects with a controllable manner. study focuses on three basic challenges defects, including (i) how introduce at dopant–host interface, (ii) control intensity of emission, (iii) tune QD color via emission. Finally, this application...
The diffusion Monte Carlo (DMC) method is used to calculate the electron binding energies of two forms (H2O)6−. It found that DMC method, when using either Hartree−Fock or density functional theory trial wave functions, gives in excellent agreement with results large basis set CCSD(T) calculations. This demonstrates will be a viable for characterizing larger (H2O)n− ions which calculations are not feasible.
Large-size luminescent solar concentrators (LSCs), which act as a complement to silicon-based photovoltaic (Si-PV) systems, still suffer from low power conversion efficiency (PCE). How improve the performance of LSCs, especially large ones, is currently hot research topic. Traditional LSCs have only single transmission mode fluorescence materials Si-PV, but here we introduce new idea absorption Si-PV by employing dual modes both and scattering light. To prepare with transmission, systems are...

Abstract CsPbX 3 (X = Cl, Br, I) nanocrystals (NCs) are competitive materials for a wide range of applications because their outstanding optoelectronic properties. Ion doping has been demonstrated as one powerful method improving the optical properties NCs. However, conventional ion‐doping approaches tedious, and generally performed under an inert atmosphere high temperature. In this work, one‐step ultrasonic‐assisted approach is to prepare doped To demonstrate universality approach, three...

Environment-friendly co-doped CsBr nanocrystals with controllable dual-emission and chrominance have been successfully prepared by using facile one-pot colloidal synthesis approach.
Large scale cesium lead-halide (CsPbX3, X = Cl, Br, and I) perovskite films have become the basis of laser applications. Common fabrication methods such as spin-coating thermal evaporation a trade-off between high quality low cost. Herein, we reported facile method for preparing large area homogeneous CsPbBr3 film via multiple centrifugal deposition solvent annealing (MCDSA) method. This is superior because it can control thickness (180 nm to 880 nm) film, ensure crack pinhole free, has (2.5...
Preparing quantum dots (QDs) with strong stability against salts is extremely important in some environments ultrahigh concentration, such as the oil exploitation, wastewater treatment and biological markers. In this paper, we reported a simple new method to prepared highly stable QDs by using multi-branched ligands. Our results suggested that ligands-capped have good dynamic even salt-saturated solution. Unlike traditional theory, which considers electrostatic repulsion of dominant QD...
