Crystal growth, structural, linear and nonlinear optical studies of 4-methyl-4′-N′-methylstilbazolium tosylate single crystals

Organic 4-methyl-4'-N'-methylstilbazolium tosylate, a new derivative of the stilbazolium tosylate family compound was synthesized by condensation method. The optical quality single crystals with dimension 5 mm x 4 mm x 2 mm were grown by slow evaporation technique at 40 degrees C. The crystal system and lattice parameters were found from single crystal X-ray diffraction studies. The optical transmittance, cut-off wavelength (402 nm) and band gap energy (3.09 eV) were estimated by UV-visible studies. The surface laser damage threshold study was carried out for MMST crystal using Nd:YAG laser. The third-order nonlinear optical susceptibility (chi(3)) for MMST crystal was estimated by employing Z-scan technique using 1064 nm laser. (C) 2013 Elsevier GmbH. All rights reserved.
