Abstract
The optical and physico-chemical properties of the photosensitive dye - thiocarbocyanine in water solution as well as entrapped into the sol-gel matrices are examined. The absorption is measured for different pH of solutions. The changes caused by addition of ethanol and triton, are also investigated. It was observed that the photostability of the dye, in both water solution and sol-gel, depends strongly on pH and temperature. The higher photostability is observed for higher pH. It is shown that for thiocarbocyanine immobilized in sol-gel matrix, the photodegradation is slower than in the case of water and alcohol solutions.
