Luminescent sensors

Head : G. Ledoux

Members: E. Homeyer

Luminescence properties from matter may depends on external factors such as temperature, pressure, pH… We use these properties to develop luminescence based sensors. We are currently focusing our attention on thermal sensors for the analysis of thermal and mechanical properties of materials. We are also involved in developing sensor in fluidic devices in order to study the cavitation phenomena. Dedicated micro-fluidic set-up developed in LEGI (Grenoble) can be plugged on our confocal microscope. Other optical technics such as Raman or Brillouin spectroscopy are also used for this purpose, mainly for sensors in optical fibers.
