摘要

Cadmium sulphide (CdS) nanoparticles were formed in l,3-bis-(P-iminobenzoic acid)indane by exposing Cd~(2+) doped Y- and Z-type multilayered Langmuir-Blodgett (LB) films to H_2S gas. The growth of CdS nanoparticles were monitored by UV-visible spectroscopy measurements. It was observed that CdS nanoparticles in both Y- and Z-type LB films cause a blue-shift in absorption spectra. The surface morphology of LB films were characterized with atomic force microscopy DC electrical measurements were carried out for these LB films grown in a metal/LB film/metal sandwich structures with and without CdS nanoparticles. By analyzing I-V curves and assuming Schottky conduction mechanism the barrier height was found to be as 1.25 and 1.17 eV for Y-type unexposed and exposed samples; 1.18 and 1.25 eV for Z-type unexposed and exposed samples, respectively.
