多路生物成像需要光谱不同的荧光团。特别是，监测活着的哺乳动物的生物过程需要在组织透明的近红外(NIR)窗口，即700到1700 nm之间工作的荧光团。在这里，我们报道了一种基于分子Er3+-细菌素络合物的荧光体系，该体系具有大的斯托克斯位移(>；750 nm)和窄带的近红外到近红外下转换光谱(半最大全宽
Spectrally distinct fluorophores are desired for multiplexed bioimaging. In particular, monitoring biological processes in living mammals needs fluorophores that operate in the 'tissue-transparent' near-infrared (NIR) window, that is, between 700 and 1,700 nm. Here we report a fluorophore system based on molecular erbium(III)-bacteriochlorin complexes with large Stokes shift (>750 nm) and narrowband NIR-to-NIR downconversion spectra (full-width at half-maximum
