Structural engineering of single-crystal-like perovskite nanocrystals for ultrasensitive photodetector applications

Abstract

Low-dimensional organic-inorganic hybrid perovskite materials have attracted much attention due to their excellent performance in optoelectronics and facile solution-processability compared with their bulk and thin-film counterparts. Herein, we successfully synthesized...

Highly Luminescent Transparent Cs2AgxNa1–xBiyIn1–yCl6 Perovskite Films Produced by Single-Source Vacuum Deposition

“…Similar strong redistributions of diffraction peaks were also reported for lead halide perovskite crystals cut/grown along different crystallographic axes 23 − 25 as well as for lead-free double-perovskite nanosheets. 26 …”

Preparation and Energy Storage Performance of Perovskite Luminescent Materials by an Electrochemiluminescence Method

“…In the 1760s, the first industrial revolution, the use of coal, freed human beings and entered the age of steam [1]. In the 1870s, the second industrial revolution, the use of electricity and oil mainly generated by burning coal, enabled human beings to learn to convert mechanical energy into electrical energy and enter the electrical age [2].…”

Growth and High-Performance Photodetectors of CsPbBr3Single Crystals

“…Lead halide semiconductors with ABX 3 stoichiometry show great advantages and application potentials in light-emitting diodes, lasers, photodetectors (PDs), memristors, solar cells, and so on due to their excellent optoelectronic characteristics. − A lot of research has been reported in the field of photovoltaics on perovskite materials, and many methods have been proposed to improve the conversion efficiency of perovskite photovoltaic devices, such as improving crystallinity, optimizing interfaces, introducing additives, etc . In perovskite devices, perovskite materials exist in various forms, such as polycrystalline films, single crystals (SCs), nanocrystals, quantum dots, etc., which also reflects the outstanding processability of perovskite . This diversity of application forms is attributed to the defect tolerance of perovskite materials.…”
