Synthesis and second-order optical nonlinearity of DAMS/Mn2P2S6 intercalated materials by ion exchange method

Intercalated hybrid materials alternating optical nonlinear organic chromophores and inorganic Mn2P2S6 layers were obtained by ion exchange method. The Mn2P2S6 powder was synthesized by solution-state combined solid-state method, which benefited for MPS3’s mass production. The reaction between Mn2P2S6 layers and inserted chromophores was intensified by UV–visible spectroscopy. It was indicated that Mn2P2S6 powders after solution-state combined solid-state method was single crystalline and DAMS molecules self-assembled in the layers of Mn2P2S6 to form J-aggregates. Second-harmonic generation (SHG) of DAMS/Mn2P2S6 thin films was observed by Maker fringe measurement. The DAMS/Mn2P2S6 intercalated material was well formed by ion exchange method.
