Research on Variety of Metal Microstructures Reduced by Assembled Quantum Dots

CdTe quantum dots (QDs) were assembled through femtosecond laser direct writing. Then metal ions were reduced by the CdTe QDs to make metal structures. The assembled CdTe QDs retains the fluorescent property and after the reduction it can obtain the metal properties. With this method we can prepare various of metals microstructure such as Ag, Cu, Zn, Pt, Cr,, Fe, etc. The conductivity of the Cu microstructure could reach 2.7 x 10(5) S/m.
