- Abstract:
- Long afterglow phosphorescent SrAl2O4 and CaAl2O4 based phosphors are found to be a useful sensor head material in the fluorescence thermometer because of extremely long fluorescence lifetime. Highly sensitive temperature sensor can be developed based on temperature dependence of afterglow intensity of long afterglow phosphor. Sensitivity of long afterglow phosphorescent SrAl2O4:Eu, Ln and CaAl2O4:Eu, Ln based phosphors are considered to be dominated by depth of the hole traps generated by doped rare-earth elements.
