EUROPEAN CONGRESS AND EXHIBITION ON ADVANCED MATERIALS AND PROCESSES - EUROMAT 2021

This research study focuses on the development of a new optical sensor platform. The device is based on a layered doped transparent ceramic pumped with a laser diode and coupled with a functionalized surface plasmon resonance (SPR) structure as an innovative photonic component for both lighting and sensing. Targeted areas are the detection of pollutants in water (Cu, Fe, etc.) or air (CO, NOx, etc.), as well as medical diagnosis.

The core of the lighting component is a doped YAG ceramic, adapted to the desired optical properties, under LED excitation. Light enhancement occurs at the device surface due to the SPR effect. For that purpose, the SPR effect is obtained by adding hybrid Au@SiO2 or Ag@SiO2 nanoparticles. In addition, a functionalized mesoporous silica topcoat is also deposited according to the targeted chemical or biological compound.

The presentation will focus on surface functionalization (nanoparticles synthesis, deposition on the surface, mesoporous silica topcoat elaboration) and detection capabilities through optical measurements based upon a demonstrator.
