英文摘要	we fabricated qd-silica-au nc hybrid spheres, in which the solid silica core contained qds while the mesostructured silica shell contained au ncs, by a two-step synthesis procedure. the hybrid spheres were further characterized by high-resolution transmission electron microscopy (hrtem), energy dispersive x-ray spectroscopy (eds), x-ray photoelectron spectroscopy (xps), fourier transform infrared (ftir) and nitrogen adsorption-desorption analysis to confirm the formation of the ternary hybrid structure. the as-prepared ternary hybrid spheres showed an interesting fluorescence spectrum variation and further could be developed as a precursor for fabricating multicolor fluorescence bar codes by using l-cysteine (l-cys) as an effective post-encoding adjuster. a small variation of the concentration of l-cys led to a prominent change of the precursor's fluorescence intensity ratio, which could correspond to a series of distinguishable multicolor fluorescent bar codes. furthermore, the multicolour fluorescence bar codes fabricated by the post-encoding method showed excellent non-reversibility, batch-to-batch reproducibility of the intensity ratios, photophysical and thermal stability properties and anti-interference capabilities, which are important virtues for them to be used in high-throughput bio-labelling and imaging.
