“…When solid electrolyte CaY 2 S 4 - 16 mol % Yb 2 S 3 is used as a membrane, reproducibil ity of sensitivity and response decreases. This can be explained by the fact that the membrane of this com position corresponds to the boundary of the domain of existence of solid solutions [1,2].…”

The work demonstrates the prospects of using solid electrolytes of CaY 2 S 4 -Yb 2 S 3 within electro chemical sensors sensitive towards hydrogen sulfide and sulfur dioxide. The range of temperature for the opti mum sensor operation is determined: 600-900 K. It is found that the suggested solid-state electrochemical sensor allows determining sulfur dioxide and hydrogen sulfide qualitatively and quantitatively in the concen tration range of 3.0 × 10 -9 to 1.0 × 10 -5 M and 3.0 × 10 -8 to 1.0 × 10 -5 M, respectively.

In this study, the structural, electronic, optical, elastic, and thermodynamic properties of Ytterbium chalcogenides YbX (X = S, Se and Te) were computed within the first principles using generalized gradient approximation (GGA) as implemented in the pseudopotential plane wave approach. The equilibrium total energy for YbX (X = S, Se, and Te) was calculated as a function of the energy cutoff, k-point grid, and lattice parameter. An optimized lattice parameter of 5.6, 5.66, and 6.136 Å were calculated for YbS, YbSe, and YbTe, respectively. The energy band gaps of YbS, YbSe, and YbTe computed are 1.14, 1.32, and 1.48 eV, respectively. In addition, the low band gap (less than 3 eV) for ytterbium chalcogenides indicated that they may have potential applications in photovoltaic cells and laser diodes. Moreover, the negative dielectric function value for a certain frequency range indicates that these compounds are suitable for specific optical and microwave circuit applications. The result of elastic and thermodynamic property computation reveals that ytterbium chalcogenides are mechanically and thermodynamically stable, which can be useful in a variety of electronic device applications.
