Lead doped chalcogenide glass compositions, in the pseudo-ternary AgI-PbS-As 2 S 3,
were examined as active membrane materials for the construction of Pb (II) ion-selective
sensors, Pb (II)− ISE. The basic glass properties of the synthesised bulk samples such as
vitreous state, macroscopic, thermal and electric properties were studied. To this end,
several techniques were used, including X-ray powder diffraction, density measurements,
differential scanning calorimetry, scanning electron microscopy and impedance complex …
