Recent progress with one-dimensional metal halide perovskites: from rational synthesis to optoelectronic applications

Abstract

Metal halide perovskites can be readily synthesized, they exhibit tunable physical properties and excellent performance, and they are heavily studied optoelectronic materials. Compared to the typical three-dimensional perovskites, morphological-level one-dimensional (1D) nanostructures enable charge transport and photon propagation with low exciton binding energies and long charge-carrier diffusion lengths, while molecular-level 1D nanostructures exhibit good compositional and structural flexibilities, highly tunable bandgaps, strong quantum confinement effects, and excellent ambient stabilities. The 1D natures of these emerging halide perovskites enhance the performance of optoelectronic devices. Herein, we highlight recent progress realized in the syntheses and characterizations of both morphological- and molecular-level 1D halide perovskites with tunable structures, compositions, and properties, as well as their photovoltaic, light-emission, and photodetection applications. In addition, current challenges, future prospects, and promising research directions are discussed to provide guidance in advancing the field of 1D perovskites.

Multichromism in Halide Perovskites

“…The 1D perovskite nanostructures are typically synthesized using wet-chemical methods, such as organic ligand-mediated growth, phase transition control, oriented attachment, and anion exchange. [91][92][93][94][95][96]97] Substrate-assisted methods, such as polymer matrix-assisted growth, dissolution-recrystallization strategy, and vapor-phase deposition, have also been used to synthesize 1D perovskite nanostructure. [98][99][100] In addition to singlephase 1D perovskite nanorods (NRs), heterojunctions of different phases have also been synthesized.…”

Multi-stimuli-responsive luminescence enabled by crown ether anchored chiral antimony halide phosphors

“…Besides, the dimensionality of HOMHs is variable, which exerts a significant impact on their luminescent properties. Shrinking the dimensionality of HOMHs from three-dimensional (3D) to low-dimensional (2D, 1D, 28 0D) can endow them with unique properties such as large exciton binding energy, multiple quantum wells and confinement effects, 29 controllable charge-carrier mobility, and efficient photoluminescence intensity. 30–32 Low-dimensional metal halides have thus been witnessed to exhibit high photoluminescence quantum yield (PLQY) and broad emission range 33 on account of the formation of self-trapped excitons (STEs).…”
