Abstract
The optical absorption characteristics of vacuum-deposited thin films of erbium and dysprosium diphthalocyanine were investigated using tran smission spectroscopy before and after exposure to chlorine gas and co mpared with previous work performed upon lead monophthalocyanine (PbPc ). Considerable red shifts in the visible absorption spectra were obse rved after Cl-2 exposure for the diphthalocyanines but not for the mon ophthalocyanine. These were interpreted on the basis of differences in molecular structure in relation to the adsorption of chlorine.
