Synthesis of normal and flattened rhombic dodecahedral Ag2S particles

Author affiliations

Abstract

Normal and flattened rhombic dodecahedral sub-micrometer Ag2S particles were synthesized by a facile hydrothermal method. The effects of molar ratio of thiourea (Tu) to AgNO3 and volume of concentrated HCl aqueous solution on the morphologies of Ag2S particles have been systematically investigated. Experimental results indicated that the formation of soluble Ag-Tu complexes was a key issue to regulate the morphology of final products. The stability and decomposition of the soluble complexes were found to be dependent on the molar ratios of Tu to AgNO3 and HCl. A body-centered cubic to monoclinic phase-transfer mechanism was proposed to explain the formation of regularly morphological Ag2S particles.
