Growth and Characterization of Semiorganic Non-linear Optical Material: (((4-aminophenyl)sulphonyl)oxy)zinc(II)chloride Crystal

Abstract

Growth and characterization of nonlinear optical (NLO) crystal of (((4-aminophenyl)sulphonyl) oxy)zinc(II)chloride (4-ASZC), based on zinc chloride with sulphanilic acid by the slow evaporation method has been studied and reported in this paper. The single crystal X-ray diffraction study confirmed the monoclinic system with centrometric space group P2 1 . The sharp Bragg's peak in powder X-ray diffraction analysis identifies the crystalline nature. Optical properties, such as low cut-off wavelength (251 nm), optical band gap (E g = 4.40 eV), reflectance (R), extinction coefficient (K) and refractive index (n), are calculated from the UV-vis-NIR spectrum. The presence of functional groups are confirmed by the FT-IR spectroscopy. The placement of protons and carbons was determined by the NMR technique. The photoluminescence study shows the green light emission. The grown crystal is thermally stable up to184°C. The NLO efficiency is 0.5 times greater than that of standard KDP. The mechanical properties were analysed. The dielectric constant (ε), dielectric loss (ε ), imaginary dielectric constant (ε ), AC conductivity (σ ac ) and Cole-Cole graphs were plotted. The surface morphology and the particle size of the crystal were determined by the FESEM technique. ARTICLE HISTORY

A Study Of Growth And Characteristics Of Metal Salt Like Manganese Sulphate [MnSO4] Doped In L Threonine Amino Acid Single Crystal For NLO Application

“…Examples of NLO materials are Barium borate, cadmium lithium borate, lithium iodate, Monopotassium phosphate, zinc oxide, Tellurium dioxide [39]. These NLO Crystals are further categories to Inorganic NLO -eg KCL, lithium niobate (LiNbO3) or potassium dihydrogen phosphate (KH2PO4) , KDP , (KTiOPO4), Barium metaborate, Methyl parahydroxyl benzoate e.t.c [40], [41].Organic NLO crystal -4-dimethylamino-N-methyl-4-stilbazolium-tosylate(DAST),2-(3-(4hydroxystyryl)-5,5-dimethylcyclohex-2enylidene)malononitrile OH1) [42].Semi organic NLO crystal -BTCC: Bis(thiourea) cadmium chloride, Bis-thiourea cobalt chloride (BTCoC),ATCC triallyl thiourea cadmium chloride, ATMB Triallyl thiourea mercury bromide,TSCCB thiosemicarbazide cadmium bromide, zinc thiourea chloride (ZTC) , 4-aminophenyl)sulphonyl)oxy)zinc(II)chloride Crystal [43], [44], [45], [46], [47] [48], Various techniques like solvent evaporation, slow cooling of the solution, solvent/ non-solvent diffusion, vapor diffusion and sublimation for crystals formation of NLO materials [1], [2], [3], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [25], [26], [27], [30], [31], [32], [33].Due to chiral carbon atom and no centrosymmetric space group, an Amino acid crystal has excellent NLO and electro optical properties. Biosynthesis pathway in bacteria & plants categorizes Amino Acid to six families as Histidine, Aromatic, pyruvate, serine, aspartate, glutamate family respectively [49].…”
