“…Figure 4 shows the DC recorded for (200) diffracting planes in symmetrical Bragg geometry by employing MCD as describe above for EBST specimen. As seen in the figure the curve is quite sharp with out any satellite peaks which may otherwise be observed either due to internal structural grain boundaries [8] or due to epitaxial layer formed on the surface of the crystal by organic dopants [9]. We measured intensity and glancing angle.…”

The organic material 4-Ethoxybenzaldehyde-N-methyl 4-Stilbazolium Tosylate (EBST) is a new NLO material and new derivative in Stilbazolium Tosylate family. In this work we synthesized the EBST, the derivative of DAST. By slow evaporation method, we have grown the EBST crystal. Powder XRD confirms the crystalline property, the lattice parameters are calculated from single crystal XRD data and the molecular structure also revealed. The crystal system is found as monoclinic. The crystalline perfection is assessed by the high-resolution X-ray diffractometry. A single and reasonably sharp peak observed in the diffraction curve indicates that the quality of the crystal is quite good without having any internal structural grain boundaries. The FTIR and proton NMR study confirm the presence of functional groups. From the UV -Vis Far IR absorption spectra the good transparency is revealed. The Kurtz Perry SHG test confirms the NLO property of the EBST crystal grown and it is 11 times greater than urea. The melting point of the grown crystal is found to be 237°C from the DSC curve.

“…The hardness test was performed for the loads varying from 25g to 100g and the stability of the crystals towards the external stresses was observed.The dielectric constant of the material can be measured using two probe method. The samples were cut and polished, thenecessary sides were coated with graphite to obtain a good ohmic contact with the electrodes.Using different temperature ranging[40 0 C to 75 0 C ]the capacitance and dielectric loss values were carried out [11] using an Agilent 4284ALCR meter for frequencies like 1KHz,10KHz,100KHz,1MHz.The dimension of the growncrystals was measured using a microscope. Air capacitances were also measured for the dimensions equal to that ofall thecrystals.…”

-The single crystal of L-Lucinedoped NickelSulphateHexa Hydrate (NSH) was grown from slow evaporation technique for different molar concentrations, viz., (0.2 to 1 mole% in steps of 0.2). The crystallinty, cell parameter and cell volume of the grown single crystals was estimated by powder X-ray diffraction studies. The mechanical power of the crystals wasstudied by Vicker's micro hardness testing. The electrical study was carried out for both pure and doped NSH crystals.

“…The incorporation of suitable additives in the solution lead to an increase in metastable zone width of the solution by their tendency of forming complexes and coordination bonds with metallic impurities present in the solution [4][5][6]. The EDTA and H 2 O 2 are the good surfactant additives, which form complexes with the metallic impurities in the solution and thereby increase the Ostwold-Mier's metastable zone with [7]. Thus the presence of EDTA and H 2 O 2 in the solution, prevent the incorporation of impurities into the growing crystal and rarely enter into the crystal lattice thereby confirm the growth of high quality crystals for device fabrication.…”
