    Annotation In this work, we study the possibility the use of Nd3+, Yb3+:CeF3/CeO2 nanoparticles in ratiometric luminescence thermometry. In order to explain the mechanism of the luminescence temperature sensitivity, we physically characterized the samples by means of transmission electron microscopy (TEM), X-ray diffraction (XRD), laser spectroscopy, and electron paramagnetic resonance (EPR). In particular, Nd3+, Yb3+:CeF3 nanoparticles were synthesized via co-precipitation method and annealed in air at 600 ◦C for 0, 15, 30, 60, and 120 min to obtain double-phase Nd3+, Yb3+:CeF3/CeO2 nanoparticles as well as single-phase Nd3+, Yb3+:CeO2 ones (at 120 min). The physical diameter of the samples gradually increases from 19 ? 2 (doped CeF3) to 409 ? 18 nm (doped CeO2). It was suggested, that the double-phase samples consist of sintered doped CeF3 and CeO2 nanoparticles having average grain diameter around 65 nm. The single-phase CeO2 sample also consists of sintered CeO2 nanoparticles, suggestively. The luminescence intensity ratio (LIR) was analyzed in the 80–320 K range (LIR = INd/IYb, where 848–925 nm (4F3/2 – 4I9/2) Nd3+ and 925–1048 nm (2F5/2 – 2F7/2) Yb3+). The maximal relative temperature sensitivity was achieved for Nd3+, Yb3+:CeO2 sample (~0.2 %/K), which is very competitive value. The LIR function has a simple linear temperature dependency in the broad 80–320 K which allows uniquely identifying the temperature at least in the studied broad temperature range. The mechanism of temperature sensitivity was suggested.
