A sonochemical method for the selective synthesis of a-HgS and b-HgS nanoparticles

A novel sonochemical method for the selective synthesis of a-HgS (cinnabar) and b-HgS (metacinnabar) nanoparticles in aqueous solutions is reported in this paper. a-HgS and b-HgS nanoparticles have been selectively prepared by choosing sodium thiosulfate and thiourea as the sulfur source respectively. To study the crystalline structure, size, morphology and composition of the products, characte...

Phase transfer-based synthesis of HgS nanocrystals.

Phase transfer techniques possess remarkable advantages for the synthesis of inorganic nanomaterials. In contrast to the abundant reports on the preparation of noble metal nanoparticles using phase transfer, the number of semiconductor nanocrystals syntheses based on phase transfer techniques is still limited. Herein, we report a systematic study of the phase transfer-based synthesis of HgS nan...
