Optical Properties of Clusters. Recently optical luminescence of InP clusters has revealed surprisingly narrow (less than one millielectron volt) spectral lines (55). Photoluminescence and cathodoluminescence has been used at the University of Lund, Sweden to excite InP imbedded between layers of GalnP (Carlsson, N. Seifert, W. Petersson, A. Castrillo, P. Pistol, M. E. and Samuelson, L., to be publishe<. STM has been used to excite some of these materials (56). The strained InP layer wifh approximately 10 monolayers of thickness spontaneously reforms into 100 nm quantum dot structures. These quantum dots luminesce at 1.6 to 1.85 eV and have demonstrated line widths of less than 0.1 meV at 77 K.

In addition to the synthesis of latexes with high solids content and small particle size, in the past decade, microemulsion polymerization has heen used to synthesize a wide range of materials. For instance, several works have incorporated inorganic materials such as carhon nanotuhes, " ZnO nanoparticles (UV absorption),montmorillonite clay, " and quantum dots (luminescence probes) " to produce nanocomposites. Furthermore, nanogels, " conductive polypyrrole and polyaniline latexes, " " polyurethanes using immiscible monomers, and polymers in water-in-scC02 microemulsions have been also prepared by microemulsion polymerization.
