Controlled synthesis of PbS nanoparticles and the deposition of thin films by Aerosol-Assisted Chemical Vapour Deposition (AACVD)

A series of symmetrical and unsymmetrical N,N-dialkyldithiocarbamatolead(II) complexes with the general formula [Pb(S2CNRR2)(2)] where R-1 = Me, R-2 = benzyl (1), R-1 = Me, R-2 = heptyl (2), R-1 = Me, R-2 = octadecyl (3), R-1 = R-2 dioctyl (4), R-1 = Me, R-2 = Hex (5), R-1 = Me, R-2 = Me (6), R-1 = Et, R-2 = Et (7), R-1 = Pr-n, and R-2 = Pr-n (8) have been prepared and characterized. All these complexes were used as single source precursors to grow PbS nanoparticles by thermolysis in oleylamine at temperature as low as 60 degrees C; lower temperatures than previously used. Compounds (1)-(4) have also been used as precursors to deposit thin films of PbS by Aerosol-Assisted Chemical Vapour Deposition (AACVD). The crystal structure of (1) has also been determined.
