Abstract

Intercalation compounds of CdPS3 with 4-[4-(dimethylamino)-α-styryl]- 1-methylpyridine cation (DAMS+) exhibit high-efficiency optical second harmonic generation (SHG). This is unexpected since the native CdPS3 host crystallizes in a centrosymmetric lattice. It is believed that the SHG results from the aggregation of the intercalate within the interlamellar spaces of the host lattice. For efficient SHG the spatial organization must have a characteristic length scale on the order of the second harmonic wavelength, or about 1 micron. We have studied the temperature dependence of the fluorescence of CdPS3:DAMS intercalation compounds and have demonstrated the presence of DAMS aggregates.
