Abstract
Linear and nonlinear optical effects have been studied in chromophore-doped gel hosts. Tetra-4-sulfonatophenylporphyrinatocopper(II) (CuTPPS), and 1,3-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.
