Thermal, optical, mechanical and dielectric properties of nonlinear optical crystal 4-methoxy benzaldehyde-N-methyl 4-stilbazolium tosylate
چکیده انگلیسی

We have grown organic nonlinear optical 4-methoxy benzaldehyde-N-methyl-4-stilbazolium tosylate (MBST) crystals by slow evaporation technique. The grown crystals were analyzed by powder XRD, FTIR, NMR, UV, Thermal, mechanical and dielectric measurements. Lattice parameters and crystallinity of the crystal is confirmed by the XRD studies. The FTIR and NMR studies give the details about the various functional groups present. In order to study the optical quality of the crystal, the UV–vis absorption spectrum was recorded and cut-off wavelength was determined. Melting point of the crystal is found from the differential scanning calorimetry. The powder SHG studies were done with the Kurtz powder technique and the NLO efficiency is 17.2 times greater than that of urea. The surface of the grown crystal was analyzed with etching. Laser damage threshold studies have been carried out for the crystal using a Q-switched Nd:YAG laser of 10 ns pulses.


► Organic nonlinear optical crystal having 17.2 SHG efficiency comparing with urea.
► Good thermal stability and laser damage threshold—efficient candidate for fabrication of devices.
► Suitable for EO modulator due to low dielectric constant and loss at high frequency.
