Growth and characterization of tris allylthiourea mercuric chloride crystals

Abstract

Single crystals of tris allylthiourea mercury chloride (ATMC), a semi-organic nonlinear optical material, have been grown from a low-temperature solution growth technique by slow cooling method. In the present work, we have grown ATMC crystal which is a new nonlinear optical material (NLO) having high optical quality and its second harmonic generation (SHG) efficiency is thrice that of Urea. The grown crystals have also been subjected to various characterization studies like X-ray diffraction, UV-VIS, FT-IR and TGA-DTA. X-ray powder diffraction study confirmed the crystal structure of ATMC, UV-VIS /FT-IR spectral analysis showed the crystal has good optical transmission in the entire visible region and TGA-DTA studies showed the thermal properties and complex degradation of ATMC crystal.

Synthesis and Characterization of L-Proline Potassium Iodide Crystal

“…Meyer gave a relation between the load (P) and average diagonal indentation length (d) as P = k 1 d n ,where k 1 is the constant depending on the material and, 'n' is Meyer's index or work hardening coefficient. Upon taking logarithm on both sides of the above relation, we get an equation of the straight line and, hence the value of work hardening coefficient (n) can be obtained [34]. The plot of log (P) against log (d) for LPPI crystal is shown in fig.…”

Growth and characterization of new semiorganic nonlinear optical zinc guanidinium sulfate single crystal

“…A further weight loss of 9.2% was observed at 581.3 1C followed by other meager weight losses of 0.59% and 0.43% at 783 and 905.3 1C, respectively. From the thermal analysis, it is evident that the ZGuS has higher thermal stability compared to other well-known semiorganic NLO crystals like L-alanine sodium nitrate (300 1C), bisthiourea cobalt chloride (185 1C), bis glycine sodium nitrate (272.2 1C), triallyl thiourea cadmium chloride (230 1C), triallyl thiourea mercury chloride (221 1C) and triallyl thiourea zinc chloride (190 1C) [11][12][13][14][15][16].…”
