Möller, Karin; Bein, Thomas; Herron, Norman; Mahler, Walter; Mac Dougall, Jim E. and Stucky, Galen D. (1990): EXAFS Analysis of Size-Constrained Semiconducting Materials. In: Molecular Crystals and Liquid Crystals, Vol. 181, No. 1: pp. 305-314 [PDF, 475kB]


Semiconducting materials such as CdSe, CdS, PbS and GaP are included in crystalline zeolite Y and mordenite and structurally flexible ethylene-methacrylic acid copolymer solid matrices. EXAFS analysis reveals formation of species with dimensions of molecular size up to ca. 13 A in the crystalline hosts, while the polymer matrices allow agglomeration of larger semiconducting particles. Zeolite anchored structures are distinctively different to small particles with bulk crystal structure as usually found in colloidal systems.
