Abstract

Layered metal chalcophosphates with the empirical formula, MPQ3 where, M is a main group element or transition metal, and Q is a chalcogen, forms a family of semiconductors, where the layers are held together by weak van der Waals forces. These materials have enjoyed considerable attention owing to their potential applications as cathode materials for secondary batteries, ion-exchange applications, ferroelectric materials, non-linear optically active materials, photomagnetic composite materials and so on. Li metal can be incorporated into these compounds very easily either by electrochemical Li intercalation or by ion-exchange reactions. LixNi1-xPS3 is already being used as cathode material in some room temperature batteries. The main goal of this project is to synthesize and characterize the growth of thiophosphate nanotubes and nanowires mainly by employing hydrothermal growth techniques. Some initial synthesis strategies for growing these thiophosphate nanowires and nanotubes would be discussed along with some preliminary data.
