Synthesis and characterization of MoSe2 and WSe2 nanoclusters

Synthesis and Characterization of MoSe2 and WSe2 Nanoclusters The synthesis, characterization, absorption, and emission spectra of MoSe2 and WSe2 nanoclusters are reported. These nanoclusters are about 3.5-6 nm (MoSe2, see graphic) and 4-7 nm (WSe2) in diameter, as measured by TEM imaging. The particles are strongly quantum confined and highly anisotropic. Electron diffraction results indicate that they are three-atoms thick, consisting of a single two-dimensional Se-MoSe or Se-W-Se trilayer.
