dc.description.abstract In this work, we present a new approach to demonstrate rewritable, light-driven recordings in polydimethylsiloxane (PDMS) by manipulating the light-induced photobleaching phenomenon [1]. The selectively photobleached red dyes turned transparent, thereby creating patterned letters that emit different colors such as blue or green, from their backgrounds. Furthermore, the diffusion of dye molecules in the bleached region promoted a self-healing characteristic that could erase the patterned letters, which could enable the rewriting of different letters using the same PDMS. Using the proposed approach, we could pattern multi-color-emitting PDMS by taking advantage of the light-induced photobleaching phenomenon that is usually regarded as an undesirable effect in microscopy research. The introduction of this novel way to realize rewritable, light-driven technology is highly meaningful because current approaches have been based on photochromic materials, which require a complex synthesis process. Using the conventional-dye-incorporated PDMS and photobleaching phenomenon for the reversible color changes would be an alternative approach to resolve the remaining challenges. We believe that this novel concept may find potential applications in many research fields, such as secure printing and optical storage devices. -
