Abstract

Nanoscale semiconducting materials such as quantum dots (0-dimensional) and one-dimensional (1D) structures, like nanowires, nanobelts, and nanotubes, have gained tremendous attention within the past decade. Among the variety of 1D nanostructures, tin oxide (SnO2) semiconducting nanostructures are particularly interesting because of their promising applications in optoelectronic and electronic devices due to both good conductivity and transparence in the visible region. This article provides a comprehensive review of the recent research activities that focus on the rational synthesis and unique applications of 1D SnO2nanostructures and their optical and electrical properties. We begin with the rational design and synthesis of 1D SnO2nanostructures, such as nanotubes, nanowires, nanobelts, and some heterogeneous nanostructures, and then highlight a range of applications (e.g., gas sensor, lithium-ion batteries, and nanophotonics) associated with them. Finally, the review is concluded with some perspectives with respect to future research on 1D SnO2nanostructures.

Highlights

One-dimensional (1D) nanoscale materials, such as nanotubes, nanowires, and nanobelts, have attracted significant attention due to their unique size- and dimensionalitydependent electrical, optical, chemical, and mechanical properties and promising applications as interconnection and functional components in designing nano-sized electronic and optical devices [1, 2]. 1D semiconductor nanostructures represent an important and broad class of nanoscale wire-like structure, which can be rationally and predictably synthesized in single crystalline form with controlled chemical composition, diameter, length, and doping level with high precision

Introduction

One-dimensional (1D) nanoscale materials, such as nanotubes, nanowires, and nanobelts, have attracted significant attention due to their unique size- and dimensionalitydependent electrical, optical, chemical, and mechanical properties and promising applications as interconnection and functional components in designing nano-sized electronic and optical devices [1, 2]. 1D semiconductor nanostructures represent an important and broad class of nanoscale wire-like structure, which can be rationally and predictably synthesized in single crystalline form with controlled chemical composition, diameter, length, and doping level with high precision. One-dimensional (1D) nanoscale materials, such as nanotubes, nanowires, and nanobelts, have attracted significant attention due to their unique size- and dimensionalitydependent electrical, optical, chemical, and mechanical properties and promising applications as interconnection and functional components in designing nano-sized electronic and optical devices [1, 2]. The manipulation of wellcontrolled precise dimensions, crystallinity, and composition of 1D nanostructures gives rise to unique properties, enabling a variety of applications that would not be possible with materials with bulk dimensionality. Of a single-molecular precursor [Sn(OtBu)4] containing preformed Sn-O bonds on gold nanoparticles, on a Si, Al2O3, and TiO2 substrates via the well-known vapor-liquidsolid (VLS) growth mechanism It is precisely controlled over chemical composition, morphology, and deposition rate. This review will conclude with some perspectives and outlook on the future developments in the 1D SnO2 nanostructures and related research areas
