Abstract
Silver and 1- or 2-chloroanthraquinone (1-CAQ or 2-CAQ) were sequentially evaporated at a temperature of 300 K at the thickness ratiotAg/tCAQ0.15. The deposited films were analyzed by means of optical absorption (IR, visible, near UV), Raman diffusion, X-ray diffraction, electron spin resonance, and X-ray photo-electron spectroscopy. The comparison of the results obtained with 2-CAQ and Ag/2-CAQ shows that no complex salt formation occurred between the Ag and the 2-CAQ superimposed layers. Using 1-CAQ under similar conditions, however, the results are in accordance with complex formation in superimposed layers with Ag. Interdiffusion and charge transfer (CT) are found to occur between silver and 1-CAQ. The degree of transfer is amplified by annealing.
