摘要
Inorganic-organic composite films for rewritable optical storage are fabricated base on the reversible luminescence modulation of ordered upconversion nanopatterns via a photochromic diarylethene. The near-IR excitation for reading the upconversion emission does not affect the recorded data bits. Moreover, the spatially well-defined 2D nanopatterns promise future applications in ultrahigh-density storage.
