摘要: Various organic laser dyes have been incorporated into organically modified silicates (ORMOSILs), derived from polydimethylsiloxane and tetraethoxysilane. These sol-gel PT-ORMOSILs proved to be good hosts for the in terms of stability optical gain. Some dyes, example, Rhodamine 610, 620, 640, shown higher than methyl alcohol. The Rh6G a PT-ORMOSIL is 76% dry nitrogen air, because contribution oxygen and/or moisture dye degradation processes. fluorescence intensity Rh610 was enhanced by factor 3.9 as temperature cooled room 77 K.
