“…Among them a semiorganic zinc(tris) thiourea sulphate (ZTS) possess good nonlinear optical properties which can be useful in high power lasers as frequency convertor and also it may be a better alternative for KDP crystals [19]. Several key properties such as morphology, growth rate, crystalline perfection, optical transparency, band gap, second harmonic generation (SHG) efficiency, laser damage threshold (LDT) are found to be enhanced/change due to some additives or dopants in ZTS as well as many other crystals [9,[20][21][22][23][24][25]. Single crystal growth with dye doping has been attracted to many researchers and scientist due to their possible applications in solid state lasers as well as many other applications [26][27][28][29][30][31][32][33][34][35][36][37][38].…”

In present work, the pure and brilliant green dye doped single crystals of nonlinear optical zinc tris(thiourea) sulfate have been grown for the first time using slow evaporation solution technique from their aqueous solutions. The powder X-ray diffraction and FT-Raman spectroscopic investigations were carried out to confirm and identify the crystal structure and vibrational modes, respectively. The strong effect of dye on crystals morphology is observed. For optical band gap analysis the diffused reflectance was measured. Two absorption bands were observed in the diffused reflectance spectrum centered at *425 and 627 nm due to brilliant green dye. Room temperature PL study with 310 nm excitation show noticeable enhancement in UV-blue emission band centered at 348 nm due to dye doping and also the enhancement in violet-blue emission centered at 420 nm was observed. Mechanical strength was also found to be enhanced with doping. All the results show that the properties of ZTS crystals are enriched due to dye doping and can be applied in optoelectronic devices.

“…The interaction of thioureas with metal ions has been the subject of several recent investigations because of their variable binding modes and because of the relevance of their binding sites to those in living systems [1][2][3][4][5][6][7][8][9][10]. The complexes of palladium(II) and platinum(II) in this regard are particularly important because some of them are known to exhibit antibacterial and antitumor activity [7][8][9][10][11].…”

Palladium(II) complexes of thiones having the general formula [Pd(L) 4 ]Cl 2 , where L = thiourea (Tu), methylthiourea (Metu), N,N 0 -dimethylthiourea (Dmtu), and tetramethylthiourea (Tmtu) were prepared by reacting K 2 [PdCl 4 ] with the corresponding thiones. The complexes have been characterized by elemental analysis, IR and NMR spectroscopy, and two of these, [Pd(Dmtu) 4 ]Cl 2 Á 2H 2 O (1) and [Pd(Tmtu) 4 ]Cl 2 (2), by X-ray crystallography. An upfield shift in the[C=S resonance of thiones in 13 C NMR and downfield shift in N-H resonance in 1 H NMR are consistent in showing sulfur coordination with palladium(II). The crystal structures of the complexes show a square-planar coordination environment around the Pd(II) ions with the average cis and trans S-Pd-S bond angles of 89.64°and 173.48°, respectively.
