Abstract

Photochromic and thermochromicanus have been encapsulated in an organic-inorganichybrid network, produced by theSol-Gel method. It was found that the photochromic anils have been transformed to thermochromic, something observed for the first time in rigid glasses. Spectroscopic investigations indicate a common infrastructure responsible for the coloured xerogel.
