| description | Abstract Current optical storage technologies utilizing phosphor media face challenges in achieving rapid and precise data recording with visible or infrared light, primarily due to the constraints of traditional charging techniques. Here, we introduce a cutting-edge method termed up-conversion charging (UCC) to address these challenges, enabling rapid and high-resolution data storage in phosphors. Our study focuses on the unique two-step ionization and non-linear charging characteristics of UCC in storage phosphors, specifically in a gallate composition Gd3Ga5O12:Cr3+. Remarkably, this technique enables data writing with high solution, requiring only 0.01 s of exposure per bit when utilizing a portable laser engraver equipped with visible-emitting diode lasers. The present strategy not only enhances recording efficiency but also ensures long-term data retention and superior rewritability. Moreover, we illustrate the versatility of UCC storage across various material systems through thermally- and optically-stimulated luminescence. Our outcomes highlight the transformative potential of the UCC method in advancing optical storage applications, offering significant improvements in the development of information storage solutions. |
