主 题:polymer pen lithography upconversion luminescence nanoparticle array ligand
摘 要:We report a high-throughput approach to generating lanthanide-doped upconversion nanoparticle(UCNP)arrays through polymer pen lithography(PPL),where instead of the expensive block co-polymer,two types of polymers are employed with one working as ink carrier,e.g.,polyethylene glycol-400(PEG-400)to facilitate smooth transfer from the tip to the substrate and the other,e.g.,polyvinyl pyrrolidone(PVP),as chelator to ensure successful patterning of metal *** strong coordination of PVP with rare earth ions(RE^(3+))is the key for weakening the interaction between RE3+ions and the carrier PEG-400 so that the good mobility of ink can be *** experimental results have shown that besides PVP,small molecules with functional groups that can coordinate with RE^(3+)ions,such as oleic acid,can also serve the same role as PVP,which greatly enriches the ink library for *** 1 cm^(2)area arrays comprising individual UCNP can be reliably generated with characteristic upconversion *** strategy not only allows reliable production of individual UCNP arrays,it also paves new avenue to the precise synthesis of multifunctional NPs for lasing,imaging,encryption,and anticounterfeiting.
