Synthesis of [(H3O)Tm3F10] · nH2O, ErF3, and TmF3 powders and their physicochemical properties

Exploration of structural, thermal and spectroscopic properties of self-activated sulfate Eu2(SO4)3 with isolated SO4 groups

“…According to the SEM observation, the obtained europium sulfate product is mostly formed by To see the thermal stability range for Eu2(SO4)3, the TG/DSC measurements were implemented. It is well known, that rare earth salts precipitation from aqueous solutions inevitably leads to the formation of a mixture of crystalline hydrates [70,71]. Then, the main problems in the anhydrous salts formation by the thermal decomposition of their crystalline hydrates are the complete removal of all crystalline hydrate water molecules and the absence of pyrohydrolysis processes [72,73].…”

Synthesis of Samarium OxysulfateSm2O2SO4 in the High-Temperature Oxidation Reaction and Its Structural, Thermal and Luminescent Properties

“…As it is known from the reported results, the initial material granules, under certain conditions, are able to maintain the original shape and size in the thermal decomposition process [28][29][30]. At the same time, the compounds with the stoichiometric lanthanide ion content attract attention in order to find efficient luminescent materials with low concentration quenching and to investigate specific mechanisms of luminescence quenching in them [31][32][33][34][35][36][37][38][39][40]. At the same time, the consideration of lanthanide-containing materials cannot be restricted only by their luminescent properties.…”

The nature of the interaction of RE(NO3)3 (yttrium subgroup) with HF or NH4F

“…In the temperature range of 50-200 °C, a gradual loss of mass is observed, which corresponds to the evaporation of adsorbed water and water located in the internal cavities of the diamond-like structure. [11,26] The water content in the structure of the compound depends on the composition of the compound, its structure, and the time and temperature of drying the sample.…”

“…Rare earth fluorides (REF 3 ) are produced by chemical [8,10,11] and physicochemical [12][13][14][15] methods. Synthesis of nanofluorides can be performed using one of the following methods: pyrolysis method of fluorine-containing precursors; hydrothermal synthesis; micro-emulsion method; solvo-thermal synthesis; sol-gel technique.…”
