The structure, optical and conducting properties of thin vacuum deposited films of erbium bisphthalocyanine (Pc2Er) and its mixtures with metal-free phthalocyanine (H2Pc) have been studied with particular reference to the near infrared (NIR). It has been found that, in spite of intense optical absorbance over the UV/Vis/NIR domain, pure Pc2Er films are weakly photoconductive. However, in the mixed Pc2Er/H2Pc films the photocurrent signal was detected in the NIR range of 1200–1500 nm, which is associated with optical activity of Pc2Er molecules.
