Abstract The rapid advancement of nanotechnology has sparked much interest in applying nanoscale perovskite materials for photodetection applications. These are promising candidates next-generation photodetectors (PDs) due to their unique optoelectronic properties and flexible synthesis routes. This review explores the approaches used development use devices made different architectures, including quantum dots, nanosheets, nanorods, nanowires, nanocrystals. Through a thorough analysis recent literature, also addresses common issues like mechanisms underlying degradation PDs offers perspectives on potential solutions improve stability scalability that impede widespread implementation. In addition, it highlights encompasses detection light fields dimensions other than intensity suggests avenues future research overcome these obstacles fully realize state-of-the-art systems. provides comprehensive overview guides efforts towards improved performance wider applicability, making valuable resource researchers.

Capitalizing on rapid carrier migration characteristics and outstanding photoelectric conversion performance, halide perovskite memristors demonstrate an exceptional resistive switching performance. However, they have consistently faced constraints due to material stability issues. This study systematically employs elemental modulation dimension engineering effectively control with different dimensions A-site elements. Compared pure 3D 2D perovskites, the quasi-2D memristor, specifically BA0.15MA0.85PbI3, is identified as optimal choice through observations of (HRS current < 10–5 A, ON/OFF ratio > 103, endurance cycles 1000, retention time 104 s) synaptic plasticity characteristics. Subsequently, a comprehensive investigation into various aspects, including paired-pulse facilitation (PPF), spike-variability-dependent (SVDP), spike-rate-dependent (SRDP), spike-timing-dependent (STDP), conducted. Practical applications, such memory–forgetting–memory recognition Modified National Institute Standards Technology (MNIST) database handwritten data set (accuracy rate reaching 94.8%), are explored successfully realized. article provides good theoretical guidance for synaptic-like simulation in memristors.

We report a facile, solvent-free surfactant-dependent mechanochemical synthesis of highly luminescent CsPbBr3 nanocrystals (NCs) and study their scintillation properties. A small amount surfactant oleylamine (OAM) plays an important role in the two-step ball milling method to control size emission properties NCs. The solid-state synthesized perovskite NCs exhibit high photoluminescence quantum yield (PLQY) up 88% with excellent stability. capped different amounts were dispersed toluene mixed polymethyl methacrylate (PMMA) polymer cast into scintillator discs. With increasing concentration OAM during synthesis, PL CsPbBr3/PMMA nanocomposite was increased, which is attributed reduced NC aggregation quenching. also varied loading studied resulting most intense observed from 2% perovskite-loaded disc, while 10% loaded disc exhibited highest radioluminescence (RL) 50 kV X-rays. strong RL may be deep penetration X-rays composite, combined large interaction cross-section high-Z atoms within shows peak centered at 536 nm fast decay time 29.4 ns. Further, we have demonstrated X-ray imaging performance NC-loaded disc.

Two-dimensional (2D) organic–inorganic hybrid perovskites have been extensively investigated due to their simple synthesis methods and unique optoelectronic properties. Compared three-dimensional (3D) perovskites, 2D an alternating arrangement of organic inorganic layers, resulting in inherent anisotropy structure. Besides, the layer can act as a hydrophobic barrier, which isolate being contacted with water oxygen, thus allowing them be stable air. Therefore, excellent candidates for linear polarization-sensitive photodetectors. Moreover, layered structure, it is easy integrate other or nonlayered materials construct heterostructures without taking lattice matching among two into consideration. In this Review, structural optical properties are first discussed. The photodetectors based on then introduced. Further, potential applications illustrated. Last, current challenges field summarized, research directions proposed.
