Tris thiourea Zinc(II)sulphate (ZTS) and rare earth Yttrium(III)Nitrate doped Tris thiourea Zinc(II)sulphate compounds were synthesized from aqueous solution and single crystals were grown from aqueous solution by slow evaporation technique. The unit cell parameters of the grown crystals were evaluated by single crystal X-ray diffraction analysis. Powder X-Ray diffraction patterns were recorded and indexed for the structural confirmation. The functional groups present in the crystals were analyzed, using the Fourier transform infrared (FTIR) spectral analysis. EDX analysis revealed the incorporation of the Yttrium ions (Y3+) entered into ZTS crystals. UV-Visible transmission spectrum has been recorded to determine the cut-off wavelength of grown crystals for nonlinear applications. TG–DTA studies show thermal stability of the grown crystals. The microhardness studies on the grown crystals revealed that the hardness increases with applied load for all the grown crystals. From the value of work hardening coefficients, it was found that ZTS and Yttrium(III)Nitrate doped ZTS crystals belong to the category of soft materials. The crystal perfection and quality have been identified by etching studies. The dielectric measurement exhibits the dielectric constant and dielectric loss of the grown crystals decrease with increase in frequency. The nonlinear optical properties of pure and Yttrium(III)Nitrate doped ZTS crystals were confirmed by Kurtz-Perry powder method using Nd:YAG laser source..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
