Abstract: | Cadmium complex ofn-octadecyl succinic acid (ODSA) in Langmuir films at air/water interface has been studied using surface pressure-molecular
area (π - A) and surface potential-molecular area (ΔV - A) isotherms. The metal complex formed, transferred as LB film onto solid substrates, was analysed using FT-IR and was subjected
to sulphidation reaction. Antisymmetric and symmetric carboxylate stretching vibrations have been used to determine the nature
of the ODSA/cation complexes. CdS formed after sulphidation of the cadmium complex (ODSACd) showed possible single-electron
phenomenon indicating the nanosized nature of clusters formed. Atomic Force Microscopy (AFM) measurements carried out confirmed
the size of these CdS clusters. |
