Ultralong Bi2S3 nanoribbons have been synthesized by a solvothermal process, using a mixture of aqueous NaOH solution and glycerol as the solvent. These nanoribbons (see Figure) are 50–300 nm wide, 20–80 nm thick, and up to several millimeters long, and the initial formation of the precursor polycrystalline NaBiS2 phase is crucial to their formation. The nucleation and growth process was interpreted as a solid–solution–solid transformation.

“…1D nanostructures of single-crystalline Bi 2 S 3 have been prepared by various approaches, such as, a solvothermal (including hydrothermal) process, [6] template-directed procedure, [7] and a high-temperature evaporation method. [8] However, the quality of the as-synthesized 1D nanostructures of Bi 2 S 3 from the previously reported solvothermal process in a single solvent (including water) was still unsatisfactory, because they were usually characteristic of nanorods with very small lengths (less than 5 mm) and low aspect ratios.…”

This article describes a facile solvothermal method by using mixed solvents for the large-scale synthesis of Bi(2)S(3) nanoribbons with lengths of up to several millimeters. These nanoribbons were formed by a solvothermal reaction between Bi(III)-glycerol complexes and various sulfur sources in a mixed solution of aqueous NaOH and glycerol. HRTEM (high-resolution transmission electron microscopy) and SAED (selective-area electron diffraction) studies show that the as-synthesized nanoribbons had predominately grown along the [001] direction. The Bi(2)S(3) nanoribbons prepared by the use of different sulfur sources have a common formation process: the initial formation of NaBiS(2) polycrystals, which serve as the precursors to Bi(2)S(3), the decomposition of NaBiS(2), and the formation of Bi(2)S(3) seeds in the solution through a homogeneous nucleation process; the growth of Bi(2)S(3) nanoribbons occurs at the expense of NaBiS(2) materials. The growth mechanism of millimeter-scale nanoribbons involves a special solid-solution-solid transformation as well as an Ostwald ripening process. Some crucial factors affect nanoribbon growth, such as, solvothermal temperature, volume ratio of glycerol to water, and the concentration of NaOH; these have also been discussed.

“…To demonstrate the optical properties of the synthesized product for potential applications in blue lasers and light-emitting diodes, we measured the UV-visible (vis) absorption spectra of this ZnS architecture and an example is shown in Figure 3a. It is known that the relationship between absorption coefficient (a) near the absorption edge and optical bandgap (E g ) for direct interband transitions obeys the following relation: [31] …”

Branched assemblies of nanostructures (nanocrystals, nanowires, nanobelts and nanotubes) as building blocks for functional materials and devices are the key to tailoring properties for specific applications in micro-/nanoelectromechanical systems, optoelectronics, field emitters, and light-emitting diodes. [1][2][3][4][5] Direct fabrication of complex nanostructures with controlled structural characteristics (including morphology, dimensionality, surface architectures, and crystal structures) represents a significant challenge in the field of nanometer-scale science and technology. Intensive efforts have been devoted to achieving desired morphology or shape (such as cones, spheres, tubes, wires, belts, cables, and branched heterostructures) and crystallinity of various inorganic crystals-from micrometer to nanometer size. Such structural parameters represent key elements that determine their electrical, optical, and field-emission (FE) properties. High-quality field emitters are very desirable for applications in a wide range of FE-based devices such as flat-panel displays, parallel-electron-beam microscopes, vacuum microwave amplifiers, and X-ray sources. To date, various FE cold cathode 1D nanostructural materials, such as carbon nanotubes, ZnO, ZnS, Si, SiC, CdS, and AlN nanostructures, have been demonstrated as candidates for achieving a high FE-current density at low electric fields because of their high aspect ratios.[6] Especially, branched nanostructures with a high packing density and highly crystalline nanotips can significantly enhance their FE properties and thus show great promising for practical applications. Recently, special architectures, such as AlN nanoarchitectures, [2] comblike ZnO nanostructures, [7] ZnO nanoarchitectures, [8] cactus-like Ga 2 O 3 Nanostructures, [9] CdTe architectures, [10] and branched ZnS-In heterostructures, [11] have been observed and have shown improved FE properties.ZnS, a wide bandgap semiconductor with a gap energy of 3.7 eV at 300 K, is one of the first discovered compound semiconductors and probably one of the most important materials in electronic/optoelectronic industries with prominent applications in flat-panel displays, sensors, lasers, and photocatalysis. [12,13] Interest in FE from ZnS has been increasing because of its charming performance. Many studies have been reported on manipulating the size, morphology, and crystal structure of ZnS materials for optimizing their FE properties, and various ZnS nanostructures, such as rods, [14] wires, [15] belts, [16][17][18] cables, [19,20] tubes, [21] tetrapods, [22] helices, [23] and conelike structures, [24][25][26] are synthesized. However, understanding of self-assembled single-phased ZnS branched architectures and their associated FE properties is limited, [11] although such information is vital for their potential applications.In this Communication, we report a novel single-phased ZnS branched architecture, self-assembled through a facile thermal evaporation process. This novel architecture consists of a singl...
