Synthesis, growth and characterization of nitramino sulphonic acid (NASA) NLO single crystals

New laser NLO (nonlinear optical) inorganic material nitramino sulphonic acid (NASA) [H2N2SO5] was synthesized and confirmed by NMR and XRD spectral analysis. NASA crystal was grown from aqueous solution by slow solvent evaporation technique at room temperature. Single crystal XRD revealed that NASA crystallizes in noncentrosymmetric space group Pba2. The structural purity was confirmed by powder XRD. The crystalline perfection of the grown crystal was analyzed by High resolution XRD. The optical transmittance and band gap energies of the crystal were studied by UV–vis–NIR spectral analysis. Polarizability factors attributing to dielectric properties were analyzed by dielectric studies. Second harmonic generation efficiency was also studied by Kurtz–Perry powder technique. Explosive sensitive destable nitramino bond was converted to optically energetic by stabilizing NNO2 bond within sulphonic acid host molecules.
