Abstract

Single crystals of antimony thiourea bromide with molecular formula Sb[CS(NH₂)₂]₂Br₃ (ATB) have been grown in gels at ambient temperature. Linear optical properties of this material such as refractive indices, birefringence and absorption characteristics were measured in the wavelength range 200 nm - 1400 nm. No dispersion of the birefringence was observed within the experimental accuracy. Optical second harmonic generation (SHG) of Nd:YAG laser (λ = 1.064 μm) has been observed for ATB crystal. In order to reveal the origin of non-linear optical property crystal structure of ATB has been determined. The non-linear optical property in ATB is due to the polar axis of the packing.
