Abstract: AgInS2 microspheres were synthesized via a simple solvothermal route using biomolecule L-cysteine-assisted methods. The L-cysteine both as sulfur source and complexing agent plays an important role in the formation of AgInS2 microspheres. The morphology, structure, and phase composition of the as-prepared AgInS2 products were studied through X-ray diffraction, field emission scanning electron microscope, energy dispersive X-ray spectroscope, X-ray photoelectron spectroscope, transmission electron microscope, and high-resolution transmission electron microscope. The Results showed that the as-prepared AgInS2 microspheres were orthorhombic phase with average diameters of about 2 μm. In addition, the effect of reaction temperature on morphology of the product was investigated, and a possible growth mechanism of the AgInS2 microspheres was also determined based on electron microscope.
