Highly crystalline and well-dispersed TiO2 nanorods have been prepared by well-controlled solvothermal reactions and applied to fabricate inorganic/polymer hybrid ultraviolet photodetectors. The incorporation of TiO2 nanorods could substantially improve device performance because of the widespread interface area between two components and yield a very promising device performance of high ultraviolet photo-to-dark current ratio of nearly three orders of magnitude with short response time of less than 200 ms. The proposed method provides a new route for fabricating low-cost, environmentally friendly hybrid bulk heterojunction ultraviolet photodetectors.
