Abstract

Abstract : Multi‐dye‐sensitized upconverting nanoparticles (UCNPs), which harvest photons of wide wavelength range (450–975 nm) are designed and synthesized. The UCNPs embedded in a photo‐acid generating layer are integrated on destructible nonvolatile resistive memory device. Upon illumination of light, the system permanently erases stored data, achieving enhanced information security.
