Sb2S3 microcrystallites with a wealth of novel morphologies (patterns) have been prepared by a solvothermal reaction between antimony trisulfide and thiourea (thiosemicarbazide, thiocarbohydrate) at low temperature (140degreesC/150degreesC). The typical morphologies are feather-like, radioactive dendrite-like, prism-sphere-like, prickly sphere-like, flower-like and plate-sphere-like. Close inspections revealed that all these novel complicated patterns are composed of I -D building blocks. It was found that reaction parameters, such as sulfur source, solvent, reaction temperature and time, play important roles in the morphology control of Sb2S3 microcrystallites. (C) 2003 Elsevier B.V.
