“…The energy distance between the two levels 2 H 11/2 and 4 S 3/2 of Er 3+ is small and these two levels exist in a state of thermal equilibrium, thus their populations fulfill the Boltzmann’s distribution 36 . And then the FIR of these two green emissions is temperature dependent.…”

YNbO4 phosphors with various Er3+ and Yb3+ concentrations were synthesized via a traditional high-temperature solid-state reaction method. Their crystal structure was investigated by means of X-ray diffraction (XRD) and Rietveld refinements, and it was confirmed that the obtained samples exist in monoclinic phase. The Er3+ and Yb3+ concentration-dependent up-conversion (UC) luminescence was studied under 1550 nm excitation. By inspecting the dependence of UC intensity on the laser working current, it was found that four-photon and three-photon population processes were co-existent for generating the green UC emissions in the samples with higher Yb3+ concentrations. In addition, it was observed that the temperature sensing properties of YNbO4: Er3+/Yb3+ phosphors were sensitive to both Er3+ and Yb3+ doping concentrations. Furthermore, based on the obtained temperature response of the UC luminescence phosphors, 1550 nm laser-irradiation-induced thermal effect was studied, and it was discovered that the sample temperature was very sensitive to the doping concentrations of Er3+ and Yb3+ and the excitation power.

“…Compared with conventional temperature measurement methods, the non-contact FIR technique could offer excellent temperature measurement accuracy and is especially suitable for the temperature detection in the electromagnetically and thermally harsh environments [7]. The temperature sensing behaviors of different RE 3+ such as Er 3+ , Tm 3+ , Ho 3+ and Pr 3+ used as temperature probes have been widely reported [8][9][10][11][12][13][14]. Among these ions, Er 3+ is the most popular one for temperature sensing due to its two special thermally coupled energy levels 2 H 11/2 and 4 S 3/2 with a small energy gap of about 770 cm -1 .…”

“…The phosphor sensitivity is a key factor in temperature sensing and is used to evaluate the sensor performance. Based on the temperature sensor of Er 3+ , the sensitivity ( S ) can be expressed as follows:,

true S = \frac{d R}{d T} = C e^{(- Δ E / k T)} ((), Δ E / k T^{2})

EDTA was used as chelating agent to synthesize Er 3 + , Yb 3 + codoped NaYF 4 phosphor by hydrothermal process. The crystallographic structures were characterized by X-ray Diffraction (XRD). The morphologies were analyzed by field emission scanning electron microscopy (FE -SEM). It can be known that with the increase of the EDTA/Re 3 + , the crystalline phase of samples change from α phase to the β phase. The temperature-dependent up-conversion emission spectra of the samples have been tested by the 980 nm laser excitation. Temperature sensing properties of samples were studied based on the fluorescence intensity ratio for two thermally coupled levels 2 H 11/2 and 4 S 3/2 of Er 3 + . The results show that the optical temperature sensing sensitivity increased gradually along with the EDTA/Re 3 + increasing, no matter the samples are α phase or β phase. And the sensitivity maximum of α phase samples is 0.00419 K À 1 (at 486 K, EDTA/Re 3 + = 3), the sensitivity maximum of β phase samples is 0.00466 K À 1 (at 550 K, EDTA/Re 3 + = 8). But the relative sensitivity has nothing to do with the amount of EDTA, only related to the crystalline phase. The relative sensitivity maximum of α phase samples is about 0.0105 K À 1 (at 303 k), the maximum relative sensitivity of β phase samples is about 0.0120 K À 1 (at 303 k). So, temperature sensing properties of β phase are better than that of α phase.Experimental section introduces the steps of hydrothermal synthesis of Er 3 + Yb 3 + co-doped NaYF 4 phosphors; the instruments and parameters of measuring XRD, SEM, emission spectra and temperature control.
