STRUCTURAL, XRD, FTIR STUDIES OF TITANIUM OXIDE DOPED KDP CRYSTALS GROWN BY GEL MEDIUM

Potassium dihydrogen Phosphate (KDP) crystals are one of the most popular crystals for Non-linear Optical (NLO) applications. Optically good quality pure and metal doped KDP crystals have been grown by microbial free gel growth method at room temperature and their characterization have been studied. Gel method is a very simple method and can be utilized to synthesize crystals which are having low solubility. KDP is a representative of hydrogen bonded materials which possess very good electro – optic and nonlinear optical properties in addition to interesting electrical properties. Due to this interesting properties, we made an attempt to grow pure and Titanium Oxide doped KDP crystals in various concentrations (0.002, 0.004, 0.006) using gel method. The grown crystals were collected after 15 days. We get crystals with good quality and shaped. The dielectric constants of metal doped KDP crystals were slightly decreased compared to pure KDP crystals. FTIR, XRD and SEM analyses also done. Results were discussed in detail
