Abstract We have obtained a set of sample crystals of the family of Tutton’s salt comprise in the isomorphic series with general chemical formula (NH 4 ) 2 Ni x Co (1−x) (SO 4 ) 2 ·6H 2 O, by employing growth from solutions by slow evaporation technique. The samples crystals were characterized by ICP-AES, X-ray powder diffraction analysis, thermogravimetric analysis, UV–Vis-NIR, Raman and FTIR spectroscopy. This type of material has been studied because of its physical and chemical properties not yet understood and they have potential technological applications. Chemical analysis of the samples by ICP-AES method allowed us to investigate the efficiency of the method of growth used. Thermogravimetric analysis provides the information about the thermal stability of the obtained crystals for high temperature applications, and powder X-ray diffraction analysis at ambient and high temperature reveals the structural quality and structural change of the samples respectively. We have used Raman spectroscopy in the range 100–4000 cm −1 and FTIR spectroscopy in the range 400–4000 cm −1 to understand the internal vibrational mode of the octahedral complexes [Ni(H 2 O) 6 ] 2+ and [Co(H 2 O) 6 ] 2+ , SO 4 2− and NH 4 + tetrahedra. The transmittance of our mixed ammonium nickel cobalt sulfate hexahydrate (ACNSH) crystals is 75% in the UV region, which indicates that they are ideal to use in UV light filters and UV sensors.

用于紫外光应用的铵镍钴硫酸盐的生长和表征

摘要 我们通过生长获得了一组同晶系列的塔顿盐样品晶体,其化学通式为 (NH 4 ) 2 Ni x Co (1-x) (SO 4 ) 2 ·6H 2 O。通过缓慢蒸发技术从溶液中提取。通过ICP-AES、X射线粉末衍射分析、热重分析、UV-Vis-NIR、拉曼和FTIR光谱对样品晶体进行表征。这种类型的材料由于其物理和化学性质尚不清楚,并且具有潜在的技术应用,因此已被研究。通过 ICP-AES 方法对样品进行化学分析使我们能够研究所用生长方法的效率。热重分析提供了有关高温应用所获得晶体的热稳定性的信息,常温和高温下的粉末X射线衍射分析分别揭示了样品的结构质量和结构变化。我们使用了 100-4000 cm -1 范围内的拉曼光谱和 400-4000 cm -1 范围内的 FTIR 光谱来了解八面体配合物 [Ni(H 2 O) 6 ] 2+ 和 [Co (H 2 O) 6 ] 2+ 、SO 4 2- 和NH 4 + 四面体。我们的混合铵镍钴六水合物 (ACNSH) 晶体在紫外线区域的透射率为 75%,这表明它们非常适合用于紫外线滤光器和紫外线传感器。我们使用了 100-4000 cm -1 范围内的拉曼光谱和 400-4000 cm -1 范围内的 FTIR 光谱来了解八面体配合物 [Ni(H 2 O) 6 ] 2+ 和 [Co (H 2 O) 6 ] 2+ 、SO 4 2- 和NH 4 + 四面体。我们的混合铵镍钴六水合物 (ACNSH) 晶体在紫外线区域的透射率为 75%,这表明它们非常适合用于紫外线滤光器和紫外线传感器。我们使用了 100-4000 cm -1 范围内的拉曼光谱和 400-4000 cm -1 范围内的 FTIR 光谱来了解八面体配合物 [Ni(H 2 O) 6 ] 2+ 和 [Co (H 2 O) 6 ] 2+ 、SO 4 2- 和NH 4 + 四面体。我们的混合铵镍钴六水合物 (ACNSH) 晶体在紫外线区域的透射率为 75%,这表明它们非常适合用于紫外线滤光器和紫外线传感器。
