Long lifespan of optical data memory in nanoplasmonic hybrid glass composites. a Young’s moduli (Y) of the nanoplasmonic hybrid glass with different inorganic percentages. Inset: Transmission electron microscope image of the nanoplasmonic hybrid glass composites. b Lifespan of the gold nanorods in the nanoplasmonic hybrid glass composites with different Young’s moduli. Standard deviations are represented by error bars. c Simplified effective energy barrier model of the data memory with gold nanorods
