✦ Synopsis

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.
