Abstract

This short note provides proof of the visible light photochromism of polycrystalline V₂O₅ using much simpler method than that in previous report [S. Nishio and M. Kakihana: Chem. Mater. 14 (2002) 3730]. It was found that the "doughnut-shape" coloration in polycrystalline V₂O₅ samples is formed around a direct laser spot visible laser irradiation; that is, the depth of coloration attains its maximum with increasing laser power. This effect can be a consequence of light and heat having opposite actions (coloration and bleaching, respectively) on polycrystalline V₂O₅. The result is clear evidence of photochromism based on the definition of the term.
