Metastable Phases Freezing from Melts of Reciprocal Systems PbX + CdI_2 = CdX + PbI_2(X = S, Se, Te)

摘要

Transformations in ternary reciprocal systems PbX + CdI_2 = CdX + PbI_2(X = S, Se, Te) that cause the freezing of metastable lead iodide polytypes and metastable ternary compounds were for the first time. Metastable phase diagrams were constructed for these system. The luminescent properties of stable and metastable lead polytypes and metastable compound Pb_4SeI_6 were studied.
