Emerging as an inevitable outcome of the big data era, long data are the massive amount of data that captures changes in the real world over a long period of time. In this context, recording and reading the data of a few terabytes in a single storage device repeatedly with a century-long unchanged baseline is in high demand. Here, we demonstrate the concept of optical long data memory with nanoplasmonic hybrid glass composites. Through the sintering-free incorporation of nanorods into the earth abundant hybrid glass composite, Young's modulus is enhanced by one to two orders of magnitude. This discovery, enabling reshaping control of plasmonic nanoparticles of multiple-length allows for continuous multi-level recording and reading with a capacity over 10 terabytes with no appreciable change of the baseline over 600 years, which opens new opportunities for long data memory that affects the past and future.

基于增强的杨氏模量的纳米等离子混合玻璃复合材料的大容量光学长数据存储器。

长数据是海量数据的必然结果，它是捕获长时间内真实世界变化的海量数据。在这种情况下，迫切需要在单个存储设备中以百年不变的基线重复记录和读取几TB的数据。在这里，我们演示了纳米等离子体混合玻璃复合材料的光学长数据存储的概念。通过将纳米棒无烧结地掺入富含稀土的混合玻璃复合材料中，杨氏模量提高了1-2个数量级。这一发现可以重塑多长度等离子体纳米颗粒的形状，从而可以进行连续的多级记录和读取，容量超过10 TB，在600年内基线没有明显变化，
