| Popis: | Sol-gel derived hybrid organic-inorganic materials show attractive properties as alternative media for optical data storage in the frequency domain. Doping of the matrix is easily achieved by dissolving different types of organic dyes in appropriate amounts in the clear sols, obtained via cohydrolysis and -condensation of 3-glycidoxypropyl-trimethoxysilane and aluminium-tri (secondary butylate). By evaporating volatile solvents and drying the resulting gel at room temperature, the dyes are trapped in the hybrid network. Surprisingly narrow spectral holes in the absorption bands of the dyes were generated by photophysical or photochemical hole-burning at very low temperatures. For dihydroxyanthraquinone/YbCl3-complexes the measured holewidth of 2,1 GHz at 3,94 K is about 1/5 of that found for the same complex in an ethanol/methanol glass. |
