## Abstract The optical properties of rhodamine B dye molecules confined in porous silica are reported. Porous silicaβlaser dye composite is obtained by simple impregnation of porous silica (PS) in rhodamine B (RhB) solution. The FTIR spectroscopy shows penetration of rhodamine molecules in the mat
Organically modified silicates (Ormosils), derived from silica and polydimethylsiloxane (PDMS), have been prepared by the sol-gel method with ultrasonic irradiation. Tetraethoxysilane (TEOS), PDMS, water and HC1 were mixed and exposed to 20 kHz ultrasonic waves under various conditions. Ultrasonic i
