Abstract
The temperature-measuring transducer of a temperature-measuring system that includes a device for emitting energizing radiation, a temperature-measuring transducer which, upon excitation by the energizing radiation, will emit luminescent light, a detector for detecting the luminescent light emitted by the temperature-measuring transducer, and at least one optical fiber interconnecting the various elements is made of a crystalline sensor material which contains luminescent ions, at least some of these luminescent ions being so located in the crystal lattice of the sensor material that for each of said at least some luminescent ions each immediately adjacent anion substantially shows inversion symmetry in relation to that luminescent ion.
