Abstract

Layers of Q-state particles (< 50 Å) were prepared by exposure of Langmuir-Blodgett (LB) films of cadmium arachidate to H2S to yield cadmium sulfide particles in a lattice of arachidic acid. The onset of absorption of this layer is blue-shifted by 0.38 eV with respect to bulk CdS. The adherence to Beer's law and insensitivity of the absorbance edge to the number of LB layers deposited (up to seven) suggest no strong electronic interactions between successive layers. Ellipsometric measurements show that exposure of the LB films of cadmium arachidic acid to H2S gas results in an increase in thickness of about 3 Å per layer.
