By using an amphiphilic organic solvent 1,4-dioxane, both charge generation materials (CGMs) of chlorodiane blue (CDB) and titanium oxide phthalocyanine (TiOPc) as well as charge transport material (CTM) N,N'-diethyl-4-amino-benzaidehyde-1-phenyl-1'-alpha-naphthylhydrozone (BAH) were uniformly dispersed in a polycarbonate (PC) matrix. The fabricating conditions, such as solvents, components, and device configurations that affected the photoconductive property, were examined. The single-layered photoreceptors based on these composites showed higher photosensitivity in comparison with those of dual-layered photoreceptors. Experimental results indicated that TiOPc pigment was significantly sensitized by CDB, and gave rise to synergetic enhancement in photosensitivity. (C) 2002 Elsevier Science B.V. All rights reserved.
