Abstract

Lacunary compounds of the phosphotungstates show photo -chromic and -catalytical activities allowing them to be used in radiation dosimeters and waste treatment devices. In this project we intend to develop new manganese and nickel lacunary compounds coordinated to heterocycle ligands in order to enlarge their absorption spectral range and enhance the photochromic and photocatalytic activity of thin films bearing these compounds.
