“…At the same time, it also sets a precedent for the synthesis of chalcogenides under low-temperature solvothermal conditions. The chalcogenides can be synthesized in many ways, including high-temperature solid-state method, − molten flux methods, , electrochemical synthesis, and solvothermal synthesis. − In recent years, several new synthesis methods have emerged, such as ionothermal synthesis , and surfactant-thermal synthesis. − A large number of thiogermanates were synthesized by solvothermal synthesis because this method has the advantages of low temperature, simple equipment, and perfect crystal growth.…”

The chalcogenides Cs 2 CdGeSe 4 (1), Cs 2 Hg 2 GeSe 5 (2), and Na 3 RbCu 8 Ge 3 S 12 (3) were synthesized by solvothermal condition. Germanium chalcogenides containing transition metals have flexible crystal structures. Compound 1 has a one-dimensional (1-D) chain structure consisting of anionic chain ∞ 1 {[GeCdSe 4 ] 2− } and Cs + cations. Compound 2 is a zero-dimensional (0-D) cluster structure consisting of anionic clusters of [GeHgSe 5 ] 2−and Cs + cations. Compound 3 is a three-dimensional (3-D) network structure consisting of a copper-rich [Cu 8 Ge 3 S 12 ] 4− anion and Na + and Rb + cations. Transition metal compounds with inorganic frameworks have abundant optical and electrical properties. We explored the photocurrent response of compounds 1−3. There are remarkable photocurrent densities for compounds 1−3, especially 1 with a density of 180 μA/cm 2 , which is superior to most germanium chalcogenides.

Crystalline lanthanide compounds have broad application prospects in the field of photoelectric properties. In this paper, we report the surfactant-thermal method to prepare three novel lanthanide chalcogenidostannates, [Eu(trien)(tren)(Cl)]2Eu2Sn2S9·H2O (1) (trien = triethylenetetramine, tren = tris(2-aminoethyl) amine), [Nd(trien)2Cl]HgSnSe4 (2), and [Sm(trien)(tren)Cl]Hg2SnSe5 (3), by applying poly(ethylene glycol)-400 (PEG-400) as the reaction medium. 1 crystallizes in the orthorhombic crystal system Pmmn, whereas 2 crystallizes in Pna21 in the noncentrosymmetric orthorhombic space group, and powder second-harmonic-generation (SHG) measurement reveals that the SHG response exhibited by compound 2 is roughly half as intense as that observed in AgGaS2, and 3 crystallizes in the monoclinic crystal system P21/m. 1 is the first example of Eu3+ ions being introduced into a purely inorganic skeleton; in 2 and 3, the transition metal (TM) ion Hg2+ is incorporated into the [Sn x Q y ] n− (Q = S/Se) system to form complex TM-chalcogenidostannate anions. 1, 2, and 3 exhibit band gaps of 2.13, 2.01, and 1.98 eV, respectively. Notably, all three compounds display impressive photocurrent densities, with compound 3 standing out with a density of 54 μA/cm2. Compounds 1–3 showed remarkable photodegradation of methyl blue (MB), especially compound 3, which had a degradation efficiency of 61.1%. To gain a deeper understanding of the correlation between their optical properties and their electronic structures, theoretical calculations were conducted.
