Аннотация:
Films of supersaturated substitutional Cd$_x$Pb$_{1-x}$S ($0.03 \leqslant x \leqslant 0.22$) solutions with a $B1$-type structure based on lead sulfide cubic lattice
were produced by chemical bath co-deposition of CdS and PbS with various concentrations of cadmium acetate in the ammonium citrate
reaction mixtures. The results of X-ray measurements showed that with increasing cadmium acetate concentration the microstrains increase
in the deposited layers and the crystallites have [200] preferred orientation and pronounced volume anisotropy. It is shown that the obtained
films are nanostructured. Depending on the solid solution composition, the layers consist of crystallites with average sizes 200–1000 nm.
These, in turn, are formed from initial nanoparticles with diameter 50–70 nm. The conductivity of the films decreases with increasing
cadmium-sulfide content. The synthesized films are photosensitive without any special sensitization procedure in the visible and near-infrared
spectral ranges. The maximum of spectral characteristic and the long-wave limit of the photo-response of Cd$_x$Pb$_{1-x}$S films move smoothly
toward the short-wave spectral range from 3.1 to 1.6 $\mu$m and from 2.5 to 1.2 $\mu$m, respectively, with an increase in the substitution level of lead
into cadmium in PbS lattice correspondently.
