The photoluminescence of trivalent europium (Eu³⁺) ions in the vicinity of nanometer-sized gold (Au) particles in glasses has been investigated. Au nanoparticles, synthesized in liquid, are introduced into a borosilicate (B₂O₃-SiO₂) glass matrix together with Eu³⁺ ions via a sol-gel route. Polyvinylpyrrolidone (PVP) is utilized to control the size and protect the Au colloids. It is revealed that a heat treatment of the gel at 400°C leads to a great enhancement of Eu³⁺ fluorescence under a long ultraviolet excitation, which is six times higher than without polymer-protected Au nanoparticles. We shall also discuss the effects of a broad photoluminescence due to carboynyl moieties (>C=O) attached in the protective polymer and energy transfer from >C=O to Eu³⁺ ions in enhanced local fields around Au nanoparticles.
