Abstract

We have grown a single crystal of Ascorbic acid (a drug) containing Potassium nitrate as an additive by aqueous solution method. Good semi transparent, semi organic nonlinear optical crystals were obtained in a period of 3 weeks. The cell parameters of the grown crystals were estimated by single crystal X-ray diffraction analysis. The X-ray powder diffraction further confirms the crystalline properties of the grown crystals. Thermal analysis was performed to study the thermal stability of the grown crystals. The presence of functional groups and mode of vibrations were identified from the FTIR spectrum. The powder second harmonic generation (SHG) of the grown crystal was measured by Kurtz technique using Nd: YAG laser. Scanning Electron Microscopic (SEM) studies reveals the morphology of the crystals.
