Size-quantised semiconductor cadmium chalcogenide particles in Langmuir–Blodgett films
The generation of quantised-state (Q-state) particles of CdS, CdSe, CdTe, CdSxSe1–x, CdSxTe1–x and CdSexTe1–x in polymerized nonacosa-10, 12-diynoic acid Langmuir–Blodgett (LB) films is described. The use of mixed surfactants and mixed counterions Cd2+ and Ca2+ in the LB films is shown to influence the size of the particles formed. The possible factors controlling the particles formed. The possible factors controlling the particle size obtained in LB films are discussed.
