Abstract: Dye 597 pyrromethene incorporated silica gel host/organically modified silicates (ORMOSILS) was synthesized by sol-gel process using N, N-dimethylformamide (DMF), ? -glycidoxypropyltrimethoxysilance (GLYMO) and Dimethylsalfoxide (DSMO) as a drying control chemical additive (DCCA). Silica sols were prepared using DMF, and ORMOSILs were made using GLYMO and DMSO. Absorption and emission spectra of two host samples were recorded during the sol-gel transition and effect drying time from the date of preparation. The change in absorption/emission spectra of dye doped Silica gel has been shown during the sol-gel transition in comparison to ORMOSILs. The lasing performance of both dye doped silica and ORMOSILs was shown to be different. The effects of DCCA in Silica/Ormosils on optical and lasing properties of the molecule were discussed.
