Resumen

We use 395 nm ultraviolet radiation to excite the matrix of barium hafnate doped with europium ions to develop an optical temperature sensor. Luminescent analysis as a function of temperature was performed in the physiological range. The Emission spectra showed significant variations in luminescent intensity at all transitions, obtaining a relative sensitivity of 1574.3/T2, when the temperature of the material increases from 289.7 to 323.8 K. The 5D0 —> 7F2 transition presented the better temperature resolution (1.1 × 102 K).
