Abstract
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.Keywords
