Abstract

Novel organic nonlinear optical (NLO) material 3-hydroxybenzaldehyde (3HBA) single crystals have been grown by modified vertical Bridgman technique using the single and double wall ampoules with nano translation. Single crystal X-ray diffraction analysis reveals that 3HBA crystallizes in orthorhombic system and the powder X-ray diffraction (XRD) pattern was indexed. Fourier transform infrared studies confirm the functional groups of the crystal. The optical property of the grown crystal was analyzed by UV-vis-NIR and photoluminescence (PL) spectral measurements. The thermal property of the grown crystal was analyzed by thermogravimetric (TG) and differential thermal analyses (DTA). The dielectric measurements were carried out with four different frequencies at various temperatures ranging from 308 to 373K and the results indicate an increase in dielectric parameters with the increase of temperature at all frequencies. The NLO property of 3HBA was analyzed by second harmonic generation (SHG) studies.Copyright © 2011 Elsevier B.V. All rights reserved.
