Preparation of Q-state particles in Langmuir-Blodgett films

Abstract

This review details the methods used in the production of a range of Q-state semiconductor and metal particles in Langmuir-Blodgett films, and describes some of the many methods used to characterize the particle-films. Chalcogenide based semiconductor particles can be grown in Langmuir-Blodgett films by cycles of immersion in a solution containing the appropriate metal cation and exposure to a chalcogenide gas. The preparation of metal chalcogenide (MX, where X = O, S, Se, Te) particles is discussed in terms of mechanistic insights into particle formation and growth. In particular, research investigating the role of the metal ion coordination sphere in the rate of particle formation and the ..
