Laser-induced fluorescence of europium-doped yttrium oxide for remote high-temperature thermometry
Abstract
The refractory, Y2O3, doped with Eu, is suitable for high-temperature surface thermometry when activated by a UV laser. The 612-nm fluorescence lifetime has a logarithmic dependence with temperature from about 700(0)C to beyond 930(0)C. Many applications are possible, with specific emphasis on rapidly rotating turbine components operating at high temperatures.
