One-Step Synthesis of Shelled PbS Nanoparticles in a Layered Double Hydroxide
— Core/shell PbS/S nanoparticles are synthesized in one step by UV irradia51- 194 Matrix.
tion of Mg3Al(OH)8{[Pb(S2O3)2]0.5} for 10 h. The samples are characterized by XRD,
TEM, UV/VIS, and PL spectroscopy. The presence of amorphous shells affects the optical properties of the nanocrystals, probably due to a surface modification. The use of
Mg1-xAlx(OH)2{[Pb(S2O3 )22 ]x/2·mH2O} precursors allows to precisely control the load
of the nanoparticles in the solid state matrix by simply controlling the Mg:Al ratio in
the precursor. This control is important for creating quantum dot-based optical devices.
