文摘
CdTe nanowire networks were assembled in standard physiological phosphate-buffered solution from individualCdTe nanocrystals on a time scale of minutes. TEM study revealed a chainlike internal structure of nanowirescomposed of nonfused CdTe nanocrystals. Individual wires within the network preserved the brightluminescence of CdTe nanocrystal building blocks, with remarkable changes in recombination kinetics forthe entire nanowire network, along the single wires and at intercrossing and branching points as revealed bymicrophotoluminescence and fluorescence lifetime imaging microscopy.
