Tin (II) selenide is an inorganic chemical compound of tin from the group of selenides .
Extraction and presentation
Tin (II) selenide can be obtained by reacting tin with selenium at 350 ° C.
However, there are also known other ways of presenting organotin compounds.
properties
Tin (II) selenide is a steel-gray solid that is insoluble in water. The compound occurs in two crystal structures , the normal temperature variant of which has an orthorhombic crystal structure (a = 11.50 Å, b = 4.15 Å and c = 4.44 Å).
use
Tin (II) selenide is a (IV-VI) semiconductor with a narrow band gap and is of great interest in areas such as low-cost photovoltaics and storage switching devices.
