“…Several studies reported that doping of specific additive have significant impact on inherent properties of ZTS crystal [12,13]. The doping effect of lithium, sodium, manganese, cadmium, nickel, magnesium, cesium, aluminum and antimony on different traits of ZTS crystal has been reported in literature [14][15][16][17][18][19][20][21]. Very recently, our research group has informed about the promising effect of Nd 3+ on crystal growth, structural, optical and electrical properties of ZTS crystal [23].…”

Present investigation is aimed to explore the single crystal growth, microhardness and third order nonlinear optical (TONLO) properties of Nd3+ doped zinc tris-thiourea sulphate (ZTS) crystal. The commercial slow solvent evaporation technique has been chosen to grow a good quality ZTS (12 mm × 0.5 mm × 0.3 mm) and Nd3+ doped ZTS (11 mm × 0.6 mm × 0.4 mm) single crystals. Vickers microhardness test has been employed to analyze the influence of Nd3+ dopant on the hardness behavior of ZTS single crystal. The TONLO effects occurring in Nd3+ doped ZTS single crystal have been evaluated by means of Z-scan technique using a He–Ne laser operating at 632.8 nm. The close and open aperture Z-scan configuration have been used to determine the nature of TONLO refraction n2 and absorption β, respectively. The magnitudes of vital TONLO parameters, such as refraction n2, absorption coefficient β, figure of merit and susceptibility χ3 of the Nd3+ doped ZTS single crystal, have been determined using Z-scan transmittance data. The n2, β, and χ3 of Nd3+ doped ZTS single crystal were found to be of the order of 10−10 cm2/W, 10−6cm/W and 10−5 esu, respectively.

“…Recently, we investigated the effect of dopant organic additives (Meenakshisundaram et al, 2006(Meenakshisundaram et al, , 2010Bhagavannarayana et al, 2006), Mn II (Bhagavannarayana et al, 2009), Ce IV (Kasthuri et al, 2010), Cs I (Muthu & Meenakshisundaram, 2012) (Rajasekar et al, 2014) and benzene on ZTS (Meenakshisundaram et al, 2009). We also synthesized a higher efficiency NLO material, the zinc cadmium thiourea complex Zn 0.625 Cd 1.375 (CS(NH 2 ) 2 ) 9 Á4SO 4 (Ramasamy & Meenakshisundaram, 2013).…”

Single crystals of molybdenum-incorporated tris(thiourea)zinc(II) sulfate (MoZTS) are grown by the slow evaporation solution growth technique. Crystal composition as determined by single-crystal X-ray diffraction analysis reveals that it belongs to the orthorhombic system with space group Pca21 and cell parameters a = 11.153 (2), b = 7.7691 (14), c = 15.408 (3) Å, V = 1335.14 (4) Å(3) and Z = 4. The surface morphological changes are studied by scanning electron microscopy. The vibrational patterns in FT-IR are used to identify the functional group and TGA/DTA (thermogravimetric analysis/differential thermal analysis) indicates the stability of the material. The structure and the crystallinity of the material were confirmed by powder X-ray diffraction analysis and the simulated X-ray diffraction (XRD) closely matches the experimental one with varied intensity patterns. The band gap energy is estimated using diffuse reflectance data by the application of the Kubelka-Munk algorithm. The relative second harmonic generation (SHG) efficiency measurements reveal that MoZTS has an efficiency comparable to that of tris(thiourea)zinc(II) sulfate (ZTS). Hirshfeld surfaces were derived using single-crystal X-ray diffraction data. Investigation of the intermolecular interactions and crystal packing via Hirshfeld surface analysis reveal that the close contacts are associated with strong interactions. Intermolecular interactions as revealed by the fingerprint plot and close packing could be the possible reasons for facile charge transfer leading to SHG activity.
