Nanoscale optical writing using far-field super-resolution methods provides an unprecedented approach for high-capacity data storage. However, current nanoscale optical writing methods typically rely on photoinitiation and photoinhibition with high beam intensity, high energy consumption, and short device life span. We demonstrate a simple and broadly applicable method based on resonance energy transfer from lanthanide-doped upconversion nanoparticles to graphene oxide for nanoscale optical writing. The transfer of high-energy quanta from upconversion nanoparticles induces a localized chemical reduction in graphene oxide flakes for optical writing, with a lateral feature size of ~50 nm (1/20th of the wavelength) under an inhibition intensity of 11.25 MW cm⁻². Upconversion resonance energy transfer may enable next-generation optical data storage with high capacity and low energy consumption, while offering a powerful tool for energy-efficient nanofabrication of flexible electronic devices.

使用远场超分辨率方法的纳米级光学写入为大容量数据存储提供了前所未有的方法。然而，当前的纳米级光学写入方法通常依赖于具有高束强度，高能量消耗和短器件寿命的光引发和光抑制。我们展示了一种基于共振能量从镧系元素掺杂的上转换纳米粒子到氧化石墨烯的纳米级光学写入的简单且广泛适用的方法。来自上转换纳米粒子的高能量子的转移引起用于光学写入的氧化石墨烯薄片的局部化学还原，在11.25 MW cm ^-2的抑制强度下，侧向特征尺寸为〜50 nm（波长的1/20）。上转换共振能量转移可以实现具有高容量和低能耗的下一代光学数据存储，同时为柔性电子设备的节能纳米加工提供强大的工具。
