An investigation of the characteristics of temperature-dependent fluorescence of a Cerium Ytterbium (Yb(3+))- doped silica fiber (CYDF) is presented. A 0.3-m long CYDF is diode-pumped at 976 nm and the fluorescence intensity is measured against the fiber temperature. It is observed that the fluorescence intensity decreases linearly with the increase in temperature due to the enhancement of non-radiative transition as well as the quenching of the Ytterbium luminescence. The sensitivity of the sensor is obtained at 0.0024 mW/A degrees C with a linearity of more than 98% in the range of room temperature to 250A degrees C. The proposed sensor is compact, low-cost and has long-life. It can also be combined with a wide range of existing fiber-optic multiplexing schemes that can simultaneously detect multiple physical parameters.
