Comparative Studies On Single Crystals Of Aluminium Ammonium Sulfate, Guanidinium Carbonate, Guanidnium P-nitrophenolate, Bis (guanidinium) 5-sulfosalicylate

In recent research technology, NLO crystal plays the wide role in biological, pharmaceutical and optoelectronic fields. The present study involves bulk single crystal of materials used in both active and passive modes in order to produce devices directly on bulk grown slices of material, as substrates in epitaxial growth, are discussed respectively. Single-crystal material usually provides superior properties of polycrystalline or amorphous equivalents. The various bulk growth techniques are outlined, together with specific critical features and examples are given for the types of materials and their current typical sizes, grown by these techniques. The wide range of materials used in the current research were (NH4) Al(SO4)2, C2H6N3O2, C7H10N4O3 and (2CH6N3 +. C7H4O6S2- H2O). The grown crystals were subjected to x-ray diffraction analysis in order to find the lattice parameter and crystal structure. Structural analysis by single crystal XRD analysis reveals the crystals studied belongs to Cubic, Tetragonal and Orthorhombic systems. The second harmonic generation (SHG) efficiency of grown crystals is found. Dielectric constant, uv- vis studies, microhardness and elastic constant have been studied to prove the optical nature of the materials.
