Optical, optical band gap and nonlinear optical properties of Thiourea Ammonium Chloride single crystal for nano applications
M.Uday Bhaskar,  Dr.S.Senthil Kumar,  Dr.G.Shankar
Single crystals of Thiourea Ammonium Chloride (TAC) were grown by a slow evaporation technique. The modes of vibrations of different molecular groups present in the TAC crystal have been identified by FTIR spectral analysis. The UV–vis–NIR spectral analysis is used to study the optical behaviors like absorption and transmission properties of the crystal. The optical band gap of the TAC crystal is calculated to be cut off wavelength 290nm at photon energy of 4.327eV. Finally the Non Linear Optics (NLO) property of TAC crystal was confirmed by Second Harmonic Generation (SHG) test using the Nd:YAG laser of fundamental wavelength 1064 nm.
Keywords- Thiourea Ammonium Chloride crystal, Optical band gap, Nonlinear optics, Photon energy, Second Harmonic Generation.
