摘要：

A detailed investigation of the practical spectroscopic features and the effect of prolonged exposure to elevated temperatures of an intrinsic Nd:doped fiber optic thermometer probe using the fluorescence decay time technique has been carried out. Results have shown the optimum length for the doped fiber and a maximum operating temperature of 750 degrees C, beyond which a range of high-temperature "annealing" effects are seen. These are discussed in light of the operation of the thermometers over the range from -196 to 750 degrees C and potentially above. (C) 1998 American Institute of Physics.
