Intrinsic dual-emitting doped ZnS:Mn(2+) quantum dots are promising as sole fluorophore for ratiometric sensing. The ratiometric signals are reliably output by three kinds of modulation modes, namely, electron transfer, energy transfer, and chemical reaction, respectively. Compared with a conventional QD-based pair-fluorophore system, such a comprehensively ratiometric signal readout from a single fluorophore not only means a fundamental breakthrough but will substantially simplify the design and greatly promote the application of ratiometric sensing.
本征双发射掺杂ZnS:Mn(2+)量子点有望作为比率传感的单一荧光团。比率信号分别通过三种调制模式可靠输出，即电子转移、能量转移和化学反应。与传统的基于量子点的双荧光团系统相比，从单一荧光团进行如此全面的比率信号读出不仅意味着一个根本性的突破，而且将大大简化设计并极大地促进比率传感的应用。
