Unidirectional growth, improved structural perfection and physical properties of a semi-organic nonlinear optical dichlorobis(L-proline)zinc(II) single crystal

Unidirectional growth of organic single crystals of naphthalene, anthracene and pyrene by isothermal expansion of supercritical CO2

“…3a) a very high intensity (100 000 counts per second) majorly dominating peak at 2q of 9.5 , corresponding to the (001) plane of anthracene, 34 which is evidence of a high degree of crystallinity and unidirectional growth along the (001) plane. 35 The FWHM of this peak determined from the rocking curve (reveals broadening of the XRD peak) is 0.0689 ( Fig. 3b), indicating that the crystals have less dislocation densities, minimum grain boundaries, 33,35 larger size and higher strength.…”

Bulk growth, structural, vibrational, crystalline perfection, optical and dielectric properties of L-threonine doped KDP single crystals grown by Sankaranarayanan-Ramasamy (SR) method

“…Various reports are available on the bulk crystal growth of pure and doped KDP as well as many other materials by Sankaranarayanan-Ramasamy (SR) method and various properties such as growth rate, optical transparency, crystalline perfection, laser damage threshold, mechanical and dielectric etc., were found to be enhanced in comparison to slow evaporation solution grown crystals. [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] For the pure and L-threonine-doped KDP crystals that have been grown by slow evaporation solution technique, the growth rate and various properties such as crystalline perfection, second harmonic generation efficiency, optical transparency and laser damage threshold of KDP were found to be enhanced. 36 Because of the strong effect of L-threonine (LT) doping on physical properties KDP crystals, 36 we have decided to grow As per the current available literature, there is no report on bulk growth of LT-doped KDP crystals by SR method so far.…”

Growth and characterization of NLO crystal: L-leucine phthalic acid potassium iodide

“…Meanwhile, inorganic derivatives of amino acids have proven to be the building blocks, which offered a wide choice of potential materials for NLO device fabrications [5][6][7]. L-leucine is an essential branched chain of alpha amino acid.…”
