Abstract
Fluorsceine, a dye used in lasers and non-linear optics have been studied for its interaction with crystal matrix (Sulphamic acid). Present study reveals the effect of fluorescein dye on sulphamic acid single crystals that are grown by slow evaporation solution technique at room temperature. Cell Parameters and crystal structure of pure sulphamic and 0.1 mol % fluorescein dye doped crystals is confirmed by Single Crystal XRD. The crystal structure is found to be orthorhombic and space group Pbca. Slight increase is noticed in cell parameters. Vibrational bands are assigned by FTIR and Raman spectroscopy. UV–Vis spectroscopy is also studied to find out band gap energy which is found to increase from 5.13 eV to 5.2 eV due to dye doping in crystal. Decrease in cutoff wavelength confirms that the synthesized crystals are permissible material for electro-optic application.
