Effect of Microstructural Change on the Optical Property of Ormosil Embedded Organic Molecules

ABSTRACT

In order to obtain a transparent and dimer-free Ormosil embedded with orgainc dye variations of gel struc-ture and optical properties were studied as a functiion of the change of gel composition. The Ormosils which have good optical property were produced in the 90/10 ratio of TEOS/PDMS and the structural variations of the gel were achived by the change of ratio of HCl/TEOS. As the ratio of HCl/TEOS was increased pore size of the Ormosil enlarged and porosity increased. Increasing HCl concentration led to gradually lower trans-mittance values. In the xerogel doped with the organic dye Rhodamine 6G perchlorate a dimer peak near 500nm was observed with the increase of the ratio of HCl/TEOS

Key words: Ormosil, Dimerization, Rhodamine 6G perchlorate
