In this paper,a new solvent-free crystal phase transformation approach for fabrication of nano β-form oxytitanium phthalocyanine(TiOPc) with high crystallinity and excellent photoconductive properties is reported.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 oC 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.
