摘要：

Photoconductive oxotitanium phthalocyanine (TiOPc) nanoparticles with an average diameter of 3.6 nm were successfully prepared. These nanoparticles could be well dispersed in organic solvents such as 1,2-dichloroethane to form a stable organic sol of solvent-stabilized TiOPc nanoparticles. An obvious size effect of TiOPc semiconductor was revealed by the UV-vis absorption spectroscopy measurements. Single-layered photoreceptors were prepared by coating colloidal solutions containing the C(2)H(4)Cl(2)-stabilized TiOPc nanoparticles and a polycarbonate (PC) resin onto aluminium plates. Optimum xerographic properties of the present photoreceptors were obtained on a photoreceptor containing 20 wt% of the TiOPc nanoparticles, which exhibited a photoconductive sensitivity (E(1/2)) of 0.54 mu J/cm(2) and could be positively charged to 596 V.
