Growth and characterization of Bisthiourea-zinc Acetate, a new nonlinear optical material

Growth and characterization of pure and doped bis thiourea zinc acetate: Semiorganic nonlinear optical single crystals

“…The crystallographic parameters were determined as a = 7.1217 Å, b = 17.6654 Å, c = 11.1297 Å, b = 103.16°and V = 1365.5 Å 3 for pure BTZA and a = 7.23 Å, b = 17.79 Å, c = 11.26 Å, b = 103.37°and V = 1409 Å 3 for Cd 2+ doped BTZA single crystals. Crystallographic data of pure BTZA agrees well with the literature values [14][15][16]. The crystallinity of pure and Cd 2+ doped BTZA single crystals was confirmed by powder X-ray diffraction analysis and diffraction peaks are indexed (Fig.…”

“…3a,b) shows FTIR spectrum of the synthesized pure and Cd 2+ doped BTZA single crystals. The FTIR spectrum of pure BTZA agrees well with the literature [15]. When it was compared with the spectra of thiourea [17,18], a shift in the peaks observed confirmed the metal coordination with thiourea.…”

“…Several, metal-organic complexes of thiourea such as zinc thiourea chloride (ZTC), bis thiourea cadmium acetate (BTCA) have gained significant attention in the last few years, because both organic and inorganic components in it contribute specifically to the process of SHG [11][12][13]. A three dimensional X-ray analysis has been carried out by Luigi Cavalca [14], also growth and characterization of pure BTZA were already reported [15,16] …”

Crystal structure, vibrational, and optical investigations of semiorganic nonlinear optical crystal: Bi3[CS(NH2)2]9Cl9· 2H2O

“…This shows that the binding of bismuth with thiourea is through sulfur. [11] On complexation, the contribution of C S stretching vibration becomes very small in the investigated complex and hence, the C N symmetric stretching vibration is the main contributor of this band at 1083 cm −1 . The presence of a peak at 228 cm −1 in the Raman spectrum is mainly due to the bismuth-bonded sulfur stretching band.…”

Growth, Structural, Spectral and Optical Studies on Pure and L-Alanine Mixed Bisthiourea Cadmium Bromide (LABTCB) Crystals

“…Semiorganic materials possess better thermal stability property of inorganic materials and higher nonlinear coefficient property of organic materials [1][2][3][4][5]. As we do doping in semiconductor to improve its conductivity, we dope the semi organic material with an organic material which may yield better nonlinear optical properties.They are identified as useful crystals for nonlinear optical applications in optical communication, optical switching, optical data storage, optical information processing, frequency conversion and electro-optical modulation [6][7][8][9][10][11]. The authors in the present work have tried to dope bisthiourea cadmium bromide with 1 mole % of L-alanine.…”
