Investigation on thiourea crystal grown in presence of ammonium acetate
The optically good quality single crystals of thiourea crystal grown in presence of ammonium acetate have been grown by slow evaporation solution growth technique. The single crystal X-ray diffraction and FTIR have been studied for grown crystal. The UV-Vis transmittance spectrum has been recorded in the range of 200-900 nm. Theoretical calculations have been carried out to determine the linear optical constants such as extinction coefficient and refractive index. The analysis of third order non-linear optical properties like non-linear absorption coefficient (b), non-linear refractive index (n2) and susceptibility (3) have been calculated using Z-scan technique. The dielectric and mechanical strength of doped crystals have been investigated and results are discussed.
