“…Fundamental frequencies of the pyramidal iodate ions as have been reported earlier by Nassau et al [14], Dasent and Waddington [15], Balicheva and Petrova [16], Sanyal and Nag [17], and Nyquist and Kagal [18] are in good agreement with the observed values. Table 2 represents the vibrational frequencies for the undoped and doped barium iodate crystals.…”

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 Fe 3+ and Cu 2+ . 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 Fe 3+ and Cu 2+ on the structure and nonlinear optical properties of bulk crystals was studied. Doping has no effect on the structure. Doping of Cu +2 inhibits nonlinear behavior of the substance, while Fe +3 doping of has less negative effect.

“…7, 8 and 9 respectively. Fundamental frequencies of the pyramidal iodate ions as have been reported earlier by Nassau et al [14], Dasent and Waddington [15], Balicheva and Petrova [16], Niquist and Kagal [17] Rocchiccioli [18], Dratovsky and Pacesova [19], and Nakamoto [20] are in good agreement with the observed values in the present investigation. Vibrational frequencies of undoped, Cu-doped, and Fe-doped calcium iodate crystals are given in Table 2.…”

Simple gel technique was used to grow single crystals of calcium iodate, monohydrate, by single diffusion method. For the growth of crystals, the optimum conditions were established. Crystals having different morphologies like prismatic and prismatic pyramidal were obtained. Few crystals were opaque, some were translucent and some good quality transparent crystals were obtained. Doping of Cu +2 and Fe +3 was done, to study the effect on structure, thermal and nonlinear optical properties. Cell parameters were obtained from the X-ray diffractograms. Structural analysis was done by using FT-IR spectroscopy. TGA and DTA techniques were used to carry out thermal analysis. Nonlinear optical properties were studied using SHG measurements.

“…Recently, Douglas et al further confirmed the existence of this phase on the basis of the powder XRD results [4]. Al(IO 3 ) 3 was previously synthesized by Balicheva et al, who presented the un-indexed powder XRD patterns of Al(IO 3 ) 3 [5]. However, no further crystallographic details have been given in the literature up to now.…”
