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.
