Abstract

Long-term optical data storage (ODS) technology is essential to break the bottleneck of high energy consumption for information storage in the current era of big data. Here, ODS with an ultralong lifetime of 2 10 7 years is attained with single ultrafast laser pulse induced reduction of Eu 3+ ions and tailoring of optical properties inside the Eu-doped aluminosilicate glasses. We demonstrate that the induced local modifications in the glass can stand against the temperature of up to 970 K and strong ultraviolet light irradiation with the power density of 100 kW/cm 2 . Furthermore, the active ions of Eu 2+ exhib-it strong and broadband emission with the full width at half maximum reaching 190 nm, and the photoluminescence (PL) is flexibly tunable in the whole visible region by regulating the alkaline earth metal ions in the glasses. The developed technology and materials will be of great significance in photonic applications such as long-term ODS.

表面上永久的光学数据存储在玻璃中，具有超高的稳定性和定制的光致发光

长期光数据存储(ODS)技术是当前大数据时代突破信息存储高能耗瓶颈的关键技术。通过单次超快激光脉冲诱导铕3+离子的还原和对掺铕铝硅酸盐玻璃内部光学性质的调整，获得了寿命为2 ~ 7年的ODS。我们证明了在玻璃中诱导的局部改性可以抵抗高达970 K的温度和功率密度为100 kW/ cm2的强紫外光照射。此外，eu2 +的活性离子表现出较强的宽带发射，半峰全宽达到190 nm，并且可以通过调节玻璃中的碱土金属离子在整个可见光区域灵活地调节光致发光(PL)。所开发的技术和材料将对长期ODS等光子应用具有重要意义。
