Thermal, elastic and optical properties of nanostructured Pb1−xAgxS solid solutions

For the first time, thermal, elastic and optical properties of limited Pb_1−xAg_xS (x≤0.15) solid solutions have been studied. The replacement of Pb atoms by Ag atoms in nanostructured Pb_1−xAg_xS (x≤0.15) solid solutions with cubic B1 structure is accompanied by a decrease in thermal expansion coefficient, a weak increase in elastic moduli and an increase in the band gap width E_g.
