Abstract :
Spinel crystals (Cr doped MgAl2O4) with various Cr2O3 and MgO concentrations are grown using floating zone technique for fluorescence thermometer application. Temperature dependence of photoluminescence (PL) intensity is evaluated using spinel crystal and/or composite of spinel with silicone resin. PL intensity from spinel crystal and composite decreases linearly with temperature. Spenel crystal and composite are useful as sensor materials in fluorescence thermometer.
