Abstract

Nearly mono-dispersed TOPO-capped copper sulphide nanocrystals of &lt;I&gt;ca.&lt;/I&gt; 4.5 nm (diameter) have been synthesized from [Cu(S<sub>2</sub>CNMe(<sup>n</sup>Hex))<sub>2</sub>]. The absorption spectrum of the (Cu<sub>2</sub>S) nanoparticles shows a large blue shift (2.09 eV) in relation to bulk Cu2S (1022 nm, 1.21 eV). The PL gives a broad spectrum with an emission maximum at 477 nm. The HRTEM of the nanoparticles shows clusters of particles on the copper grid with clear lattice fringes.
