title: [Study on the structure and optical limiting properties of lead(II) tetrakis (4-cumylphenoxy)-phthalocyanine doped silica gel glass composites].
abstract: The present paper reports the encapsulation of lead (II) tetrakis (4-cumylphenoxy)-phthalocyanine (PbPc(CP)4) into silica gel glass matrix to produce homogeneously doped composites by sol-gel technique. The existing state and structure of the doped PbPc(CP)4 were studied by UV-Vis absorption spectra and TEM images. Optical limiting properties were measured at 532 nm with 8 ns pulses. The results show that the doped PbPc(CP)4 molecules aggregate to form clusters in the gel glass composites, and PbPc(CP)4 has better optical limiting properties in the gel glass composites owing to the rigid structure of solid matrix.
