Extract

Marked morphology-dependent electrical, electrochemical, and spectroelectrical properties of PbS nanostructured particulate films are the subject of the present communication. Examination of the potential-dependent absorption spectra on optically transparent conducting glass supports and of the voltage-dependent capacitances and photocurrents on platinum support have revealed substantial differences between equilateral-triangular PbS (PbS-I), right-angle-triangular PbS (PbS-II), and disk-shaped PbS (PbS-III) nanoparticulate films.
