摘要: This work was carried out to synthesis a silica matrix by sol-gel technique, which used as host to Kiton Red laser dye doped with silica nanoparticles, which also prepared by sol-gel technique, to obtain KR-SiO2 nanoparticles confined in silica xerogel matrix. The rods at different pH values were successfully synthesized. The different values of pH cause different size of obtained nanoparticles, these nanoparticles act as scatter centers in the matrix. Amplified spontaneous emission (ASE), threshold pumping energy (Eth), and mean free path (lt) for photons in the rods have been reported. the results show that the values of bandwidth at full width half-maximum (FWHM) and the threshold energy are about 8.7 nm and 12 mJ respectively.
