Abstract

Thermo-sensor for a fiber-optic fluorescence thermometer has been developed using Eu doped Y₂SiO₅ (YSO) crystal grown by floating zone (FZ) technique. Photoluminescence peaking at 593 nm, 610 nm and 701 nm are observed in the crystals under illumination of UV light. 2 at% Eu doped YSO crystal is found to be the most suitable sensor material for the temperature measurement became of strong PL intensity. Peak intensity of PL from 2 at% Eu doped YSO decreases gradually with temperature from 350 K to 600 K. From these studies, Eu doped YSO crystals are useful sensor materials in fiber-optic fluorescence thermo-meter
