Abstract

The luminescence emission of Mn4+-doped magnesium titanate is strongly temperature dependent, making this material very promising for temperature sensing in the biochemical field. In this work the optical properties of the luminescence of Mg&#60;inf>2&#60;/inf>TiO&#60;inf>4&#60;/inf> are investigated for different Mn&#60;sup>4+&#60;/sup>- doping concentrations as a function of temperature. The material is then used to fabricate a fiber optic temperature microsensor, whose performance is compared to standard resistance thermometer. The potential of this material for temperature sensing is demonstrated by the high resolution of the microsensor and by its very fast response time both in the liquid and in the gas phase.
