Steady state spectroscopy and stability of tris(8-hydroxy quinoline) aluminum and ruthenium tris bipyridile chloride in sol–gel glasses

Abstract Tris(8-hydroxy quinoline)aluminum (Alq 3 ) and tris(ruthenium bipyridile) chloride (Rubpy) were incorporated each one separately and together into various sol–gel matrices, such as: zirconium oxide (ZrO 2 ), silicon oxide (SiO 2 ), silica combined with glycid-oxypropyltrimethoxysilane (SiGl), and tin oxide (SnO 2 ) prepared by the sol method. Steady state spectroscopy and photostability studies have been performed. The explanation of the photodecomposition is proposed.
