title = "Rare earth element doped ceramics and their lifetime characteristics with varying temperature",
abstract = "The fluorescent lifetimes and emission spectra of rare-earth doped ceramic materials are known to vary with temperature and several existing thermographic phosphors take advantage of this response. The behavior of three of these materials: magnesium flurogermanate (Mg4FGeO6:Mn), europium doped yttria oxide (Eu:Y2O3) and dysprosium doped ytrria alumina garnet (Dy:YAG) have been assessed and quantified as a function of temperature. The lifetimes of Mg4FGeO6:Mn and Eu:Y 2O3 decrease at lower temperatures than Dy:YAG. This behavior and the relatively larger signal to noise ratio exhibited by Dy:YAG at high temperatures, highlight Dy:YAG as a candidate for incorporation into a high temperature measurement system. Laser induced fluorescent decays initiated by an ultraviolet laser of Dy:YAG are presented for two concentrations of dopant levels. A method for temperature sensing using spectral form matching is shown for temperatures from 25 to 900 degrees Celsius.",
