1 mole % Thiourea doped Ammonium Dihydrogen Phosphate (TADP) crystals have been grown by slow evaporation technique. Vibrational frequencies of various functional groups in the crystals were derived from Fourier transform infrared (FTIR) spectroscopy. Powder X-ray diffraction studies were carried out and the lattice parameters of the grown crystals are evaluated. Their optical behaviour was examined by Ultraviolet-visible spectrum and found that the crystals are transparent in the Ultraviolet and visible region. The doped crystals are optically better and more transparent. Hence it may be very much useful for the second harmonic generation (SHG) applications.

Abstract: 1 mole % Thiourea doped Ammonium Dihydrogen Phosphate (TADP) crystals have been grown by slow evaporation technique. Vibrational
frequencies of various functional groups in the crystals were derived from Fourier transform infrared (FTIR) spectroscopy. Powder X-ray diffraction
studies were carried out and the lattice parameters of the grown crystals are evaluated. Their optical behaviour was examined by Ultraviolet-visible
spectrum and found that the crystals are transparent in the Ultraviolet and visible region. The doped crystals are optically better and more transparent.
Hence it may be very much useful for the second harmonic generation (SHG) applications.
