Abstract

Kiton red-620 impregnated transparent glasses in rod shape (length ~40mm, dia ~10mm) have been prepared by sol-gel route. The trapping of Kiton red-620 laser dye with different concentrations has taken place during the polymerization of silica-gel matrix. The prepared samples have been characterized by spectroscopic techniques such as FTIR, UV-visible, photoluminescence spectroscopy and scanning electron microscopy. The analysis of FTIR spectra shows that the dye molecules are embedded in the pores of silica gel. UV-visible study reveals that an absorption peak has been observed at about 570 nm. It has been observed that the laser dye doped silica gel rods showed sharp fluorescence peak in the visible region having red shift with concentrations. SEM micrographs exhibited that the particles of dye are embedded in the pores of silica based rods. Kiton red-620 dye doped silica based materials explore the possibility of new tunable dye lasers..
