A new study demonstrates the potential of storing data at the nanoscale using laser-enabled optical writing technology.
Researchers from the University of Shanghai for Science and Technology (USST) in China, RMIT University in Australia, and the National University of Singapore (NUS) used earth-rich lanthanide-doped upconversion nanoparticles and flakes from graphene oxide.
This material choice allowed them to circumvent the existing limitation of laser-enabled optical writing data storage, an emerging technology that has been limited by light's natural limitations up to which bits can be scaled for storage. Their study, titled "Nanoscale optical writing through upconversion resonance energy transfer," appears in the journal Science Advances.
