Reversible Luminescent Switching in a [Eu(SiW10MoO39)2]13−‐Agarose Composite Film by Photosensitive Intramolecular Energy Transfer

Transparent, flexible, self-supporting EuSiWMo/agarose composite films are fabricated by a combination of hydrogel chemistry and a casting technique, and present reversible, high-contrast luminescence photoswitching modulated by inorganic photochromic components through intramolecular resonance-energy transfer. Two-dimensional recording employing the luminescence as read-out signals is accomplished in this novel recording medium.
