A template‐free route for controlled synthesis of dumbbell‐like Sb₂S₃ microcrystals

Abstract

Large amounts of dumbbell-like Sb 2 S 3 microcrystals were synthesized via a simple solvothermal treatment method. Various techniques such as x-ray diffraction (XRD), field-emission scanning electron microscope (FESEM), high-resolution transmission electron microscope (HRTEM), selected area electron diffraction (SAED), and photoluminescence spectrometry (PL) have been used to characterize the obtained products. The results showed that the products belong to the orthorhombic Sb 2 S 3 phase, and the dumbbell-like Sb 2 S 3 microcrystals were composed by uniform microrods. Besides, the morphologies of Sb 2 S 3 microcrystals could be changed from microshperes to dumbbell-like microcrystals by only adjusting the reaction solvent. The solvent effects are discussed in detail. Furthermore, the PL properties of the obtained Sb 2 S 3 microcrystals clearly show shape effects.

Preparation of shuttle‐like Sb2S3 nanorod‐bundles via a solvothermal approach under alkaline condition

“…Currently, synthesis and morphological control of one dimensional (1D) and 1D based complex structures of Sb 2 S 3 have been extensively focused on, and various methods have been tried to grow Sb 2 S 3 nanocrystals with different morphologies [11][12][13][14][15]. At the same time, various sulfide ion sources such as ammonium sulfide, thiourea, sodium thiosulfate and thioacetamide have been employed to synthesize Sb 2 S 3 crystals.…”

Structural, Optical, and Electrical Properties of Applied Amorphized and Polycrystalline Sb2S3 Thin Films

“…Cao et al [39] showed a broad peak centered at 2.94 eV for the as-prepared Sb 2 S 3 microspheres, and Srikanth et al [40] observed the broad emission of a dominant peak at 3.43 eV for as-deposited and annealed films of Sb 2 S 3 . Further, Xu et al [41] observed a peak at around 2.06 eV for the Sb 2 S 3 microspheres and dumbbell-like microstructures, and Alemi et al [42] recorded the emission peaks at 2.99, 2.80, and 2.61eV for synthesized Sb 2 S 3 nanorods.…”

Structural and optical properties of nanocrystalline Sb2S3 films deposited by chemical solution deposition

“…However, the optical properties of these materials do also depend on the method of their synthesis. Though there are many reports available on the luminescence studies of group V-VI semiconductors in the literature [18], countable communications are available on Sb 2 S 3 with reference to its optical properties including photoluminescence [19][20][21]. Also, there are numerous reports on the synthesis of nanocrystalline Sb 2 S 3 [22][23][24], of which chemical solution deposition is one of the simplest and facile ways of preparing the nanocrystals of this material.…”
