Thulium-doped intrinsic fiber optic sensor for high temperature measurements (>1100°C) Rev. Sci. Instrum. 69, 3210 (1998); 10.1063/1.1149085Determination of local high temperature excursion in an intrinsic doped fiber fluorescence-based sensor Rev.The use of rare-earth-doped fibers for high temperature measurement has shown considerable promise. In this work, studies of the key characteristics of the performance of Er-doped fiber-based thermometer probes using the fluorescence decay time technique were carried out. Results showed the effects of fluorescence intensity as a function of doped fiber length and temporal and dopant concentration features of the probes. Annealing effects were seen to occur, and a satisfactory stable performance at up to 1100°C was reported from this material, yielding improvement on results obtained with Nd-based systems.
