Fabrication and Research of a Novel NLO Material: Tristhiourea Lanthanum Bromide
Abstract: The single crystals of tristhiourea lanthanum bromide (TTLaB) have been grown by solution growth using slow evaporation technique. The grown crystals were characterized by single crystal X-ray diffraction (XRD) to study the crystal structure. The presence of functional groups was identified through Fourier transform-infrared technique. The optical study exposed that the crystal has high transmission with lower cut off wavelength of 237.43 nm. The Elemental analysis confirmed atoms present in the grown compound. The NLO (Non Linear Optical) behavior of TTLaB crystal was tested by Kurtz-Perry powder technique. This novel semi-organic single crystal of TTLaB exhibited very good optical transmission property, high mechanical strength and large non-linearity nature.
