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.
多染料敏化上转换纳米粒子（UCNPs）被设计和合成，这些纳米粒子可以收集宽波长范围（450-975nm）的光子。将 UCNPs 嵌入光致酸产生层中，并集成在可破坏的非易失性电阻式存储器件上。在光照射下，该系统可以永久性地擦除存储的数据，从而提高信息安全性。
