Hydrazine-hydrothermal syntheses, characterizations and photoelectrochemical properties of two quaternary chalcogenidoantimonates(III) BaCuSbQ3 (Q = S, Se)

Two new phases in the ternary RE–Ga–S systems with the unique interlinkage of GaS4building units: synthesis, structure, and properties

“…These data are smaller than those of ReSe 8 Br 2 (9 μA cm −2 ), 45 CuSnSe-1 (3 μA cm −2 ), 46 [Ru(bpy) 3 ][Cd 17 S 4 (SPh) 28 ] (0.6 μA cm −2 ), 40 and ReS 8 Br 2 (0.3 mA cm −2 ), 45 but wider than those of BaCuSbS 3 (55 nA cm −2 ) 44 and BaCuSbSe 3 (30 nA cm −2 ). 44…”

“…The steady state of both compounds reached less than 1 s when the light was switched on, indicating that these two compounds possess a high transfer efficiency of photo-generated electrons and a separation efficiency of photo-generated electron-hole pairs. [37][38][39][40][41][42][43][44] Moreover, Lu 5 GaS 9 exhibits a stronger transient photocurrent response which is about 3 times larger than that of Yb 6 Ga 4 S 15 . These data are smaller than those of ReSe 8 Br 2 (9 μA cm −2 ), 45 CuSnSe-1 (3 μA cm −2 ), 46 [Ru(bpy) 3 ][Cd 17 S 4 (SPh) 28 ] (0.6 μA cm −2 ), 40 and ReS 8 Br 2 (0.3 mA cm −2 ), 45 but wider than those of BaCuSbS 3 (55 nA cm −2 ) 44 and BaCuSbSe 3 (30 nA cm −2 ).…”

Quaternary Selenides EuLnCuSe3: Synthesis, Structures, Properties and In Silico Studies

“…Quaternary selenides, comprising copper and rare earth elements, are of particular interest due to a variety of different combinations of cations that enable the design of the structural type and band gap, as well as electrical and optical characteristics [1][2][3]8,[22][23][24][25][26][27][28][29][30][31][32][33]. Recent theoretical studies well predict thermoelectric properties of the copper-derived quaternary selenides [32,34,35], which are one of the promising alternatives to traditional thermoelectric materials.…”

CsCu3SbS4: rational design of a two-dimensional layered material with giant birefringence derived from Cu3SbS4

“…Due to the introduction of alkali metals, there are two significant changes in their crystal structures: dimension reduction (from a 3D dense architecture to a 2D layered arrangement) and symmetry breaking (from a cubic crystal system to a monoclinic crystal system). So far, eight kinds of Cu-to-Sb ratios are reported in the X/Cu/Sb/Q (X = cations; Q = chalcogen) system and are listed from high to low as follows, 2.67 [e.g., [M(NH 3 ) 6 ]Cu 8 Sb 3 S 13 (M = Mn, Fe, Ni)], 12 ], 1.0 [e.g., A 2 CuSbS 3 (A = Na, K), 18 Rb 2 Cu 2 Sb 2 S 5 , 19 Cs 2 Cu 2 Sb 2 Q 5 (Q = S, Se), 20 BaCuSbQ 3 (Q = S, Se), 21 ], 0.17 [e.g., (C 4 N 2 H 12 ) 0.5 CuSb 6 S 10 ], 24 and 0.14 [e.g., Rb 2 CuSb 7 S 12 ]. 25 The detailed structural characteristics of these quaternary compounds are summarized in Table S1.…”
