“…Other studies provide insights into doped crystals of the Tutton salt family with rare-earth ions, and the properties of the emission/luminescent absorption processes of rare-earth ions were investigated and possible applications in nonlinear optics were evaluated. ,− Additionally, Abu El-Fadl et al introduced doping with small fractions of iodide ions and verified subtle changes in powder X-ray diffraction patterns, transmittance properties, thermal behavior of their samples, and unexpected second harmonic generation behaviors. In that sense, researchers who developed studies on Tutton salts are increasingly seeking to combine the properties of bivalent ions such as Co 2+ , Ni 2+ , Mg 2+ , Mn 2+ , and Cu 2+ in the crystalline structure of mixed or even doped salts in order to improve some of its properties or even discover new properties.…”

In this work, we synthesized and studied the spectroscopic properties of (NH 4 ) 2 (SO 4 ) 2 Y(H 2 O) 6 (Y = Ni, Mg) crystals doped with AgNO 3 or H 3 BO 3 . These crystals constitute a series of hexahydrated salts known as Tutton salts. We investigated the influence of dopants on the vibrational modes of the tetrahedral ligands NH 4 and SO 4 , octahedral complexes Mg(H 2 O) 6 and Ni(H 2 O) 6 , and H 2 O molecules present in these crystals through Raman and infrared spectroscopies. We were able to identify bands that are attributed to the presence of Ag and B dopants, as well as band shifts caused by the presence of these dopants in the crystal lattice. A detailed study of the crystal degradation processes was performed by thermogravimetric measurements, where there was an increase in the initial temperature of crystal degradation due to the presence of dopants in the crystal lattice. Raman spectroscopy of the crystal residues after the thermogravimetric measurements helped us to elucidate the degradation processes occurring after the crystal pyrolysis process.

“…Hence the langbeinite structure is favoured for larger alkali cations such as K, Rb (Figure 1). [12] [Fig 1 here] Little literature exists with regards to the transition metal sulfate langbeinites, with most work focusing on the optical properties of the Mg system, K2Mg2(SO4)3, doped with rare earth metals [13][14][15] .…”
