The amorphous TiOPc powder is transformed to nano-β-TiOPc by the thermal-induction under a certain temperature in a simple way. According to the research of a series of conditions related to the thermal process, we get nice nano-β-TiOPc whose crystallinity is higher than 97% at 300 ℃ for annealing 2 hours. The morphology of nano-β-TiOPc is studied by SEM and TEM. Laser organic photoconductors doped β-TiOPc as the charge generation material are prepared to detect their photoelectric performance, and the results show decent photoconductive properties.展开更多
