Influence of L-alanine Doping on Zinc (TRIS) Thiourea Sulphate (ZTS) Single Crystals

Abstract ZTS has been grown using a slow evaporation technique at ambient temperature, and the L-alanine-doped ZTS was likewise prepared. Powder X-ray diffraction (XRD), Fourier Transform Infrared spectroscopy (FTIR) and Vickers’s micro hardness test have all been used to analyse growing crystals. Both pure ZTS and L-Alanine-doped ZTS crystals have an orthorhombic structure. L-alanine doped ZTS had greater second harmonic generation (SHG) conversion efficiency. L-alanine doped ZTS crystals had a higher hardness than a pure ZTS sample. UV spectral analysis indicates that both crystals have excellent UV and visible transmission. Doping with L-alanine resulted in an increase in the melting point of the pure ZTS crystal.</jats:p

Growth, structural, optical and mechanical studies on Amino acids doped Nonlinear optical sodium acid phthalate single crystals

The slow evaporation technique was used to successfully grown amino acid doped sodium acid phthalate (NaAP) crystals at room temperature. A great deal of research has been done on the effects of amino acids on NaAP growth and characteristics. X-ray diffraction was used to examine the crystal structure and lattice parameters of the grown crystals. Functional groups were found in the title crystals, which revealed themselves utilizing FTIR spectra. The optical transparency of the doped crystals was noticed by measurements of optical absorption. In order to assess the mechanical strength of the produced crystals, Vickers microhardness tests were employed. The technique of Kurtz powder was utilized to calculate the second harmonic generation (SHG) performance of the cultivated crystals.</jats:p

Досліджено вплив амінокислот на ріст і характеристики NaAP. Для дослідження кристалічної структури та параметрів решітки вирощених кристалів використано рентгенівську дифракцію. В кристалах, які виявили себе за допомогою FTIR спектрів знайдено функціональні групи. Оптичну прозорість легованих кристалів спостерігали за вимірюванням оптичного поглинання. Для оцінки механічної міцності отриманих кристалів використано дослідження мікротвердості за Віккерсом. Порошкова методика Курца використовувалася для розрахунку продуктивності генерації другої гармоніки (ГГГ) вирощених кристалів
