摘要：

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