Abstract

Abstract : A novel strategy to design a dual mode, flexible, and highly luminescent white security paper and nanotaggants has been demonstrated. These nanofiber‐based flexible polymer mat appears white in day light, whereas emitting strong red and green colors at excitation wavelengths of 254 nm and 980 nm, respectively. These luminescent nanofibers offer a new paradigm shift from usual luminescent security features to high‐end security features to address counterfeiting problems.
