Nanoprint-based color display using either extrinsic structural colors or intrinsic emission colors is a rapidly emerging research field for high-density information storage. Nevertheless, advanced applications, e. g., dynamic full-color display and secure information encryption, call for demanding requirements on in situ color change, nonvacuum operation, prompt response, and favorable reusability. By transplanting the concept of electrical/chemical doping in the semiconductor industry, we demonstrate an in situ reversible color nanoprinting paradigm via photon doping, triggered by the interplay of structural colors and photon emission of lead halide perovskite gratings. It solves the aforementioned challenges at one go. By controlling the pumping light, the synergy between interlaced mechanisms enables color tuning over a large range with a transition time on the nanosecond scale in a nonvacuum environment. Our design presents a promising realization of in situ dynamic color nanoprinting and will empower the advances in structural color and classified nanoprinting.
基于纳米打印的彩色显示，无论是利用外在结构色还是本征发射色，都是一个快速兴起的用于高密度信息存储的研究领域。然而，先进的应用，例如动态全彩显示和安全信息加密，对原位颜色变化、非真空操作、快速响应和良好的可重复使用性都有很高的要求。通过移植半导体行业中的电/化学掺杂概念，我们展示了一种通过光子掺杂实现的原位可逆彩色纳米打印范例，该过程由卤化铅钙钛矿光栅的结构色和光子发射的相互作用触发。它一举解决了上述挑战。通过控制泵浦光，交错机制之间的协同作用能够在非真空环境中以纳秒级的过渡时间实现大范围的颜色调谐。我们的设计为原位动态彩色纳米打印提供了一个有前景的实现方式，并将推动结构色和分类纳米打印的发展。
