“…These bands are absent in the spectra of carboxylic acid salts, but there are bands in the region of ~1550-1610 and ~1300-1400 cm -1 , respectively, related to asymmetric and symmetrical valence vibrations of ionized groups of COO - [24]. If in the examined compounds the tartrate anion associated with the bismuth cation has at least one non-dissociated group -COOH, bands in the ~1700 cm -1 region should be present in the IR absorption spectra of salt [25].…”

“…Bands of valence vibrations of carboxylate groups of asymmetric νas(COO -) with a maximum at 1570 cm -1 and symmetrical vs(COO -) at 1385 and 1360 cm -1 appear, which indicates the substitution of protons in carboxyl groups of carboxylic acid for the Bi cation [29]. A wide absorption band with a maximum at 1070 cm -1 indicates the presence of dissociated oxo-groups in the compound under study [25,26]. In the spectrum of the nitrate-tartrate complex two bands are observed in this region, indicating the presence of unsubstituted protons of alcohol groups.…”

The processes of oxidative thermolysis of bismuth tartrates [Bi(NO3)(C4H4O6)]·3H2O and BiC4H3O6·H2O precipitated from bismuth nitrate solutions was studied by the methods of X-ray diffraction, thermal analysis, IR spectroscopy and chemical analysis. The staging of thermal transformation processes was determined. Morphological studies of initial precursors and the final products of their thermal transformations were carried out. The expediency of obtaining fine-crystal powders of the tetragonal bismuth oxide modification β-Bi2O3 with uniform sized particles by oxidative thermolysis of BiC4H3O6∙H2O was shown.

Nonlinear optical crystals plays important role in the field of photo electronics, optical communication, optical modulators, laser spectroscopy, frequency conversion and so on. Semi-organic crystals exhibit high NLO response, thermal stability, laser damage threshold, mechanical stability, wide optical window transmittance and structural diversity. Combinations of inorganic and organic molecules yield the semi-organic crystals. Based on its structural diversity it’s classified into three categories. In this chapter explains various kinds of semi-organic crystals and their optical, thermal, mechanical, laser damage threshold value and NLO properties and also explains the importance of these crystals in the field of optoelectronics, frequency conversion and other optical applications.

The discovery of novel organic−inorganic hybrid nonlinear optical (NLO) crystal materials holds great potential in advancing laser science and technology as they offer a wide range of benefits including easy synthesis, structural versatility, and high hyperpolarizability. Herein, the integration of L-tartaric acid (L-C 4 H 6 O 6 ) and ZnSO 4 gave rise to two acentric Zn-based organic− inorganic hybrid crystals, namely, Zn 2 (, water molecule, or [SO 4 ] tetrahedron. Interestingly, they possess moderate secondorder NLO effects of 0.28 × KH 2 PO 4 (Zn-LT) and 0.57 × KH 2 PO 4 (Zn-LTS), large birefringence of 0.075 (Zn-LT) and 0.069 (Zn-LTS), suggesting that the introduction of [SO 4 ] groups with intrinsically weak polarizability and weak optical anisotropy induces the enhancement of the NLO effect while without reducing birefringence much. In addition, both of them display UV cutoff edges near 210 nm, indicating their potential as NLO crystals applied in the UV and solar-blind region.
