Abstract :
Fluorescence thermometer using temperature dependence of fluorescent inorganic materials is studied for low temperature measurement. Various chromium ions (Cr3+) doped crystals are used as a sensor head of the fluorescence thermometer because of long photoluminescence (PL) lifetime and visible emission. In this research, various Cr3+ doped crystals are found to be useful as the sensor head for fluorescence thermometer. In addition, the ruby crystal is potentially useful material for the sensor head crystals to measure low temperature below 0°C.
