Bulk Crystal Growth and Characterization of Semiorganic Nonlinear Optical Materials

High quality bulk single crystals of novel NLO semiorganics : L-arginine tetrafluoroborate (L-AFB) and L-histidine tetrafluoroborate (L-HFB) measuring 78 × 50 × 35 mm have been successfully grown from solution by temperature lowering methods. Solubility curves of these materials have been determined in different solvents, such as water, ethanol and acetone to determine the most suitable solvent. The results of the various studies on synthesis, solvents, solubility, crystal growth, effects of seed orientation on morphologies, second-harmonicgeneration (SHG), transparency range, differential scanning calorimetry are presented. The published results of crystal growth of other analogues of LAP crystals are also presented.
