Vanadium dioxide films have long attracted attention because of the phase transition between the semiconducting state and the metallic state at 68 degrees centigrade. Vanadium oxide films have been prepared by a variety of methods, including the annealing and oxidation of evaporated vanadium under controlled conditions. In this study we explore a different route by producing amorphous and crystalline VOx films by pulsed laser deposition and annealing under a variety of conditions. We found that that in amorphous films grown at lower temperatures and then annealed, persistent photoconductivity effects can be observed, while in epitaxial crystalline films grown at high temperature, persistent effects were not observed. Furthermore, it was found that for some crystalline films persistent optical effects were observed and that optical hysteresis was dependent on the amount of time after the film anneal.
