Fractal analysis of the Rayleigh Photoinduced Light Scattering Pattern from LiNbO3:Zn Crystals

Unusual photophysical and scattering behavior is described for hyperbranched poly(phenylene sulfide) materials. These materials show interactions between the π systems of the aromatic monomer units in both ground and excited states, resulting in broad ranges for absorption and emission of light. The materials also display unusual scattering behavior; this is attributed to enhanced scattering by delocalized excited states resulting from the monomer unit interactions. This enhanced scattering is seen in the resonance Rayleigh scattering and second order scattering spectra. The ability to use these materials to construct a switch based on photoinduced scattering is demonstrated: application of ∼400 nm laser light increased scattering of 700 nm light by approximately 20%.

A series of [Formula: see text] crystals with various [Li]/[Nb] ratios (0.946, 1.05, 1.20 and 1.38) were grown by the Czochralski method. They were analyzed by inductively coupled plasma atomic emission spectroscopy (ICP-AES). As the [Li]/[Nb] ratio increases in the melt, the segregation coefficients of [Formula: see text] and [Formula: see text] ions increase, while the segregation coefficient of [Formula: see text] ions decrease. The [Li]/[Nb] ratio in the crystal of sample [Formula: see text] is 0.996, which is near stoichiometric. The dopant occupancy with different [Li]/[Nb] ratios was analyzed by IR transmission spectrum and UV-VIS-NIR spectrum. When the [Li]/[Nb] ratio reaches 1.20, the absorption peak at [Formula: see text] indicates that the threshold concentration of [Formula: see text] is 1 mol.% in the sample [Formula: see text].
