Yttria-alumino-silicate fibers heavily doped with bismuth (BI) are investigated for fluorescence temperature sensing within the interval 25 degrees C ... 500 degrees C at 750-nm (LED) excitation. High doping with Bi which resulted in a high concentration of Bi active (fluorescing) centers, is shown to permit the use of short pieces of the fibers as ``point'' sensors, which is advantageous for applications. Theoretical backgrounds of three commonly utilized sensing techniques, based on measuring fluorescence intensity ratio, fluorescence lifetime, and frequency-domain referencing, are developed and compared, aiming for effective temperature sensing using these fibers.
