METHOD OF PRODUCING STABILISED SILICON CLUSTERS Russian patent published in 2011 - IPC C01B33/02 B82B3/00

Abstract RU 2415079 C1

FIELD: chemistry.

SUBSTANCE: invention can be used in making in optoelectroics during production of solar cells. Tetrahalogensilane is reduced with an alkali metal in the presence of an ionic liquid based on di-substituted imidazolium and the dispersion of silicon particles formed is separated. The di-substituted imidazolium used is a compound of general formula (R₁-NC₃H₃N-R₂)⁺, where R₁ is selected from C₁-C₆ alkyls and R₂ is selected from C₁-C₆ alkyls.

EFFECT: invention enables to obtain stabilised silicon nanoclusters with particle size of 1-12 nm.
