本文中，基于含有多个发射带的镧系元素光官能化的M0 F膜开发了新的M0 F条形码系统。编码策略是基于通过封装含有不同量的有机染料的屏蔽层来调谐多个波段中的镧系元素MOFs的发射强度。通过控制过滤的染料负载，我们可以预测和调整的Ln 3 +@MIL-100（In）薄膜在多个波段的发射，因此产生不同的比率光学代码。这项工作突出了镧系发光MOF以可再现和稳健的方式生成条形码的机会。此外，依赖于镧系发光的光谱编码提供了优于有机荧光团和量子点的一系列优点，例如低光谱和背景干扰以及自参考。
Herein, a new MOF barcoded system is developed based on lanthanide photofunctionalized MOF films that contain multiple emission bands. The encoding strategy is based on tuning the emission intensity of lanthanide MOFs in multiple bands via the encapsulation of a screen layer containing different amounts of organic dyes. By controlling the filtered dye loading, we can predict and tune the emissions of Ln3+@MIL-100 (In) films in multiple bands and therefore give rise to distinct ratiometric optical codes. This work highlights the opportunity of lanthanide luminescent MOFs for generating barcodes in a reproducible and robust way. In addition, spectral encoding relying on lanthanide luminescence offers a range of advantages over organic fluorophores and quantum dots, such as low spectra and background interference, and self-referencing.
