Ultrasonic synthesis of nanocrystals of metal selenides and tellurides

Abstract

A mild sonochemical route was used to prepare Bi2Te3 nanocrystals, and Bi2Se2Te and Bi2SeTe2 ternary nano-alloys in aqueous solution; an interfacial mechanism for this sonochemical reaction is discussed. The basic thermoelectric properties (Seebeck coefficient) of the as-prepared nanocrystals were studied, and this simple, easy and efficient synthetic route may further encourage wider application of bismuth telluride-based alloys in solid state thermoelectric cooling devices. Furthermore, the adopted synthetic route was extended to the preparation of other nanocrystals with uniform morphologies, as well as some common but useful semiconductors.
