Bi2S3 nanoparticles and Bi19Br3S27 nanorods have been synthesized rapidly via microwave irradation in different imidazolium-based ionic liquids. The as-synthesized products were characterized by XRD, TEM and SEM. The results showed that the ionic liquids played an important role in the phase structrue and the morphology of the products. Besides, comparing experiments were further performed about the influence on morphology. The formation mechanism was discussed briefly. Moreover, the UV-Vis absorption spectra were analyzed for Bi2S3 and Bi19Br3S27 with different morphologies and nanostructures.

Key words: ionic liquid, bismuth sulfide, microwave
