“…Greyscale images have recently been demonstrated for advanced optical data storage studies. 10,12 Greyscale images were also recently demonstrated on Ba 2 SiO 4 : Eu 2+ /Ho 3+ phosphor films. This involved using a screen-printing technique for the photomask fabrication.…”

“…2 This review article showed that luminescent labelling techniques almost exclusively rely on binary images or features. In order to add further sophistication, greyscale, or multilevel images 10,11 could be created for more sophisticated luminescent labels. These typically require the use of advanced greyscale photomasks which are challenging to replicate.…”

“…For example, multiplexing approaches by exploiting the parameter space of wavelength, polarization, fluorescence intensity/lifetime, spatial domains, − etc., were carried out to tackle the challenges of memory cells miniaturization and diffraction limitation, advocating the evolution from two-dimensional to three-dimensional and five-dimensional optical storage. Nevertheless, the expansion of storage capacity is still constrained by the reliance on physically adding storage layers. − …”

In the current "big data" era, the state-of-theart optical data storage (ODS) has become a front-runner in the competing data storage technologies. As one of the most promising methods for breaking the physical limitation suffered by traditional ones, the advance of optically stimulated luminescence (OSL) based optical storage technique is now still limited by the simultaneous singlelevel write-in and readout in a same spot. In this work, to bridge the data-capacity gap, we report for the first time a novel and promising nonphysical multidimensional OSLbased ODS flexible medium for erasable multilevel optical data recording and reading. We tailor multidimensional traps with discrete, narrowly distributed energy levels through (multi-)codoping of selective trivalent rare-earth ions into Eu 2+ -activated barium orthosilicate (Ba 2 SiO 4 ). Upon UV/blue light illumination, information can be sequentially recorded in different traps assisted by thermal cleaning with an increase of storage capacity by orders of magnitude, which is addressable individually in the whole domain or bit-by-bit mode without the crosstalk by designed thermal/optical stimuli. Remarkably, good data retention and robust fatigue resistance have been achieved in recycle data recording. Insight is forged from charge carrier dynamics and interactions with traps for a universal method of data storage, and proof-of-concept applications are also demonstrated, thereby providing the way to not only rewritable multilevel ODS but also high-security encryption/decryption.
