the growth of benzophenone crystals by sankaranarayanan ramasamy sr method and slow evaporation solution technique sest a comparative investigation
Materials Research Bulletin, 2012Co-Authors: Senthil M Pandian, K Boopathi, P Ramasamy, G BhagavannarayanaAbstract:Abstract Longest unidirectional〈1 0 0〉 benzophenone (BP) crystal having dimension of 1060 mm length and 55 mm diameter was grown by Sankaranarayanan–Ramasamy method. The growth rate was measured by monitoring the elevation of the crystal–solution interface at different temperatures. The high resolution X-ray diffraction and etching measurements indicate that the unidirectional grown benzophenone crystal has good crystalline perfection and less density of defects. The Optical Damage Threshold of SEST and SR grown BP crystals has been investigated and found that the SR grown benzophenone crystal has higher laser Damage Threshold value than the conventional method grown crystal. Microhardness measurement shows that crystals grown by SR method have a higher mechanical stability than the crystals grown by SEST method. Dielectric permittivity and birefringence are high in SR grown crystal compared to SEST grown BP crystal. The UV–vis-NIR results show that SR method grown crystal exhibits 7% higher transmittance as against crystals grown by conventional method.

a comparative study on solution and bridgman grown single crystals of benzimidazole by high resolution x ray diffractometry fourier transform infrared microhardness laser Damage Threshold and second harmonic generation measurements
Crystal Growth & Design, 2006Co-Authors: N Vijayan, G Bhagavannarayana, Ramesh R Babu, R Gopalakrishnan, K K Maurya, P RamasamyAbstract:Nowadays more attention has been paid to the growth of organic nonlinear Optical single crystals due to their high nonlinear Optical efficiency and fairly good Optical Damage Threshold comparable to that of inorganic counterparts. The organic nonlinear Optical single crystals of benzimidazole (BMZ) grown by the slow evaporation solution growth technique (SEST) and the vertical Bridgman technique (VBT) were characterized, and their results have been compared. Characterization has been made by high-resolution X-ray diffractometry (HRXRD), Fourier transform infrared (FTIR), laser Damage Threshold, microhardness, and second-harmonic generation (SHG) measurement studies. The high-resolution X-ray diffraction curves (DCs) recorded by an in-house developed multicrystal X-ray diffractometer (MCD) revealed that the crystals grown by both methods contain internal structural grain boundaries. However, VBT crystals normally contain multiple low angle (tilt angle α ≥ 1 arc min) boundaries due to thermal stress caused ...
