    Nonlinear Effects in Chromophore Doped Sol-Gel Photonic Materials (1997)
    Springer
    Journal of sol gel science and technology 9 (1997), S. 169-181 
    Details
    ISSN: 1573-4846
    Keywords: aluminosilicate gel ; non-linear absorption ; metalloporphyrin ; spirooxazine ; time-resolved spectroscopy
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Linear and nonlinear optical effects have been studied in chromophore-doped gel hosts. Tetra-4-sulfonatophenylporphyrinatocopper(II) (CuTPPS),and1, 3-dihydro-1,3,3-trimethylspiro[2H-indole-2, 3′-[3H]-naphth[2,1-b][1,4]oxazine] (SP spirooxazine) species were entrapped within porous aluminosilicate hosts.Optical limiting effects and radiative up-conversion behavior in the CuTPPS-doped materials are described, and a six-level model is proposed based on experimental findings. Spirooxazine-containing specimens exhibiting photochromic effects were prepared, and cw and time-resolved spectroscopy methods are used to assess excited state band structures and the nature of guest-host interactions in the resultant gels.
