Modeling and Characterization of Microspheres with Silver Molecular Clusters for Sensor Applications

Abstract

This study explores silver-molecular-cluster-containing microspheres for advanced sensors. These microspheres are synthesized through an ion exchange process with silver nitrate and sodium nitrate, creating unique optical properties. A simulation shows an enhanced radiation interaction due to extended fundamental mode propagation. This study investigates luminescence in the visible range (400–600 nm) when excited by long-wavelength UV light (360–410 nm), offering the potential for sensing applications. These microspheres find use in environmental sensing (pollutant detection), biomedicine (drug delivery, bioimaging), and industrial process monitoring.
