The procedure involves the preparation of the Eu 3+ -doped silica gel by a sol–gel method and subsequent immersion in a silver sol (≈48 h) to allow the adsorption of Ag islands on the pore surfaces. Photoluminescence studies reveal that the enhanced fluorescence originates from a local field enhancement around Eu 3+ caused by the electronic plasmon resonance of the Ag islands. A significantly enhanced fluorescence has high potential for application in optical displays, lasers, and memory devices. — (SELVAN, S. TAMIL; HAYAKAWA, TOMOKATSU; NOGAMI, MASAYUKI; J. Phys. Chem.
