Highly stable and controllable lasing actions from PVDF encapsulated CsPbBr₃ perovskite microcrystals

Abstract

Halide perovskite (HP)-based optoelectronics, particularly lasers, have attracted considerable attention thanks to their outstanding low threshold, and tunable bandgaps. Surface coating is one of the most common strategies for significantly...

Zeolite A-Coated Mn-Doped Perovskite Quantum Dots Prepared by Vapor Deposition Crystallization for Reduction of CO2

“…As shown in Table , introducing long-chain and zwitterionic ligands to passivate the surface of QDs has acquired research focus to improve the stability of QDs for their application in electrical injection devices. − However, the ligand is highly dynamically bound to the surface of the QDs and has limited resistance to external environments (such as light and heat) . Compared with molecular-state ligands, polymer/inorganic coatings have higher stability to regulate the dynamic binding. − However, most polymers have a low thermal stability, , and with a core–shell structure, it is necessary to consider whether the lattices of the core and shell match . In addition, the use of polymers or inorganic shells to coat QDs is complicated and costly, which is not conducive to large-scale synthesis.…”

Synthesis of All-Inorganic Halide Perovskite Nanocrystals for Potential Photoelectric Catalysis Applications

“…By means of time-resolved terahertz spectroscopy CsPbBr 3 NCs have been found to possess excellent free carrier performance, with carrier mobilities of up to 4500 cm 2 V −1 s −1 and diffusion lengths greater than 9.2 µm, making for ideal intrinsic transport properties [14]. Thus, halide perovskite holds great value for optoelectronic applications and offers a wide scope 2 of 13 of prospects in high-efficiency solar cells [16][17][18], sensitive photodetectors [19][20][21], lowthreshold lasers [22][23][24], light-emitting diodes (LEDs) [25][26][27], scintillators [28][29][30], and bioimaging systems [31][32][33]. Among the multitude of applications, metal halide perovskite is particularly impressive in the field of solar cells.…”
