Study of XRD, FT-IR and Nonlinear Optical Properties of Doped and Undoped Barium Iodate Crystals Grown in Silica Gel

Sharda Shitole

Abstract—Single crystals of barium iodate were grown by simple gel technique by single diffusion method. By varying various parameters, optimum conditions for the growth were established. Crystals having different morphologies and habits were obtained. Prismatic, prismatic pyramidal, dendritic crystals were obtained. Some of them were transparent, some were transluscent, and few others were opaque. The crystals were doped by impurities such as Fe3+ and Cu2+. The formation of the compound was verified by X-ray diffractograms. The results were compared with the standard values given in JCPDS file. It confirms that the grown crystals are barium iodate, monohydrate. Structural analysis was carried out using FT-IR technique. It confirms the iodate group of the grown crystals. Nonlinear optical properties were studied by using powder second harmonic generation method. Effect of doping of Fe3+and Cu2+ on the structure and nonlinear optical properties of bulk crystals was studied. Doping has no effect on the structure. Doping of Cu+2 nonlinear behavior of the substance, while Fe+3 doping of has less negative effect.

Index Terms—Barium iodate; silica gel, doping, XRD, FT-IR, NLO properties, SHG measurements.
