Abstract

The photochromic effect under UV illumination has been studied in cluster systems of molybdenum oxides in aqueous solutions of citric acid. This paper reports the first observation of two types of systems exhibiting different photochromism. Systematic measurements of the optical characteristics, proton concentration, and photogalvanic emf have been carried out as functions of composition. A model is proposed for the molybdenum-oxide-cluster-citric-acid complex, in which intramolecular electron transfer occurs under UV illumination.
