Abstract:
The possibility of synthesis of the lead, arsenic, and bismuth chalcogenides with liquid encapsulation has been investigated. The conditions and results of the synthesis of PbSe, PbS, PbTe, Bi$_2$Te$_3$, and As$_2$Te$_3$, as well as solid solutions in the systems PbSe–CdSe and Bi$_2$Te$_3$–Bi$_2$Se$_3$ are reported. The obtained materials have been used for fabrication of thin-film photodetectors and interference filters for infrared radiation. Recommendations concerning the choice of fluxes for liquid encapsulation and the temperature conditions of synthesis are given.
