The schematic diagram of a simple set up for laser ablation in water. Lower left inset: picture of a fused quartz bowl containing the CdSe QDs in water suspension.
(a) TEM images of CdSe QDs synthesized by laser ablation in water, and inset is a magnified image showing the lattice fringes of a single crystal QD; (b) histogram of particle size distribution.
XRD pattern of CdSe QDs synthesized by laser ablation in water. The standard XRD peak positions of wurtzite CdSe are shown as vertical bars underneath the experimental data.
Photoluminescence spectrum showing CdSe QD emission at λ = 553 nm, corresponding to an average particle size of 5.4 nm.
SEM image of CdSe QD sensitized ZnO nanowires.
J-V plots of a sensitized solar cell using QDs prepared with laser ablation in water.
