Multiple logic operations based on chemically triggered upconversion fluorescence switching

Lanthanide-based logic: a venture for the future of molecular computing

“…Another example aiming at the detection of relevant ions and not only the AND gate, but also more complex logic operations, was reported by Y. Yu et al 71 An upconversion system based on NaYF 4 :Tm 3+ ,Yb 3+ as the energy transfer donor, and the Rhodamine 6G functionalized PEI (polyethyleneimine) (denoted as RFP), as the energy acceptor, was developed for sensing H + , OH − , Cu 2+ , I − and S 2− ions. The presence of amine groups in the structure of the polyethyleneimine enables the recognition of specific elements and the interaction with these molecules leads to an enhancement or quenching of the luminescence emission, due to energy transfer or electron transfer processes.…”

Multiple logic gates system based on dual‐wavelength triggered enhancing upconversion luminescence of Gd2(MoO4)3:Yb3+/Er3+

“…29,30 The physics of resin flow into a mold under pressure is similar to the seepage problem and so similar approaches have been used also to model the flow of resin into a mold containing fiber mats. 23,[31][32][33][34][35][36][37][38] The models are used in these cases to determine the resin flow front and mold filling times corresponding to different infiltration conditions.…”

“…[23][24][25][26][27] The basic logic gates relying on UC materials have been widely reported, [28][29][30] but limited reports focus on developing complex integrated UC logic gates system. [31][32] In particular, there is a strong demand for high capability information processing devices; therefore, it is necessary to develop the novel UC logic gate system capable of executing multiple logic combination operations.…”
