Synthesis of PbSe nanocrystallites using a single-source method. The X-ray crystal structure of lead (II) diethyldiselenocarbamate

Abstract

The compounds PbhSe CN(C H ) j and PbhSe CN(CH )(C H )j were synthesised and characterised. The X-ray crystal structure 2 2 5 2 2 2 3 6 13 2 of PbhSe CN(C H ) j is reported. The use of these compounds as single-molecule precursors to produce PbSe by thermolysis in 2 2 5 2 2 tri-n-octylphosphine oxide was investigated. The optical and morphological properties of the PbSe particulates were analysed; strong quantum confinement effects were observed in the optical spectra of nanodispersed PbSe in organic solvents.
