The reversed micelles of CdS nanoparticles capped with oligomer-polymaleic acid octadecanol ester (PMAO) were synthesized by a colloid chemical method in an aqueous system. The chemical ratio of PMAO between the carboxylic group and the hydrocarbon chain was controlled to 1.5:1. The PMAO-capped CdS nanoparticles were transferred on to CaF2 and Si substrates by the Langmuir-Blodgett (LB) technique. Surface pressure-area isotherms indicated that PMAO-capped CdS nanoparticles could form a stable monolayer on the water subphase. The measurement of FTIR and small angle X-ray diffraction showed that the reversed micelles of PMAO-capped CdS nanoparticles were formed with a uniform size and order in LB films. The photoluminescence properties of PMAO-capped CdS both in the solution and in the LB film indicated that the photoluminescence peaks of reversed micelles obviously changed as a result of the energy transfer from PMAO to CdS and the interaction between clusters.
