Influence of ethylene diamine tetra acetic acid on the performance of ferrous sulfate hepta hydratenon linear optical single crystal.

Optically highly transparent and colored single crystals of ethylene diamine tetra acetic acid doped with ferrous sulfate hepta hydrate (FeSO 4 ·7H 2 O), a nonlinear material, FeEDTA, has been grown from aqueous solution by slow evaporation technique. The good quality single crystals were harvested within 25 days. The grown crystals were subjected to single crystal X-Ray Diffraction and powder X-Ray Diffraction. The recorded powder diffraction pattern confirmed the purity and crystalline nature of the as grown crystal. The wide transparency seen in the recorded UV-vis-NIR spectrum proved the utility of the crystal in optoelectronics. The photoluminescence spectrum for the grown sample was also recorded. The second harmonic generation efficiency was ascertained by Kurtz and Perry powder technique. Its diamagnetic nature was confirmed by vibration spectrum magnetometer technique. [ABSTRACT FROM AUTHOR]
