“…The normalized LIR in Figure d implied that one temperature corresponds to three kinds of LIR; such method could further improve the sensing accuracy compared with single LIR. The relative sensitivity ( S r ) is a core parameter for accessing sensing ability, which can be described and deduced as the following formula: …”

Accurate measurement of temperature is extremely critical in numerous fields and has drawn widespread concern nowadays. To meet the demand of temperature sensing in nanoscale optoelectronic devices, a series of quasi-two-dimensional square Y 2 O 3 nanosheets were fabricated through a topological method with the co-doping of Bi 3+ and Sm 3+ . The intensity of Sm 3+ under 340 nm excitation was greatly enhanced, and multipeak spectra were obtained due to the energy transfer process. Moreover, the three peaks in temperature-dependent emission spectra exhibited different changing trends. The mechanism of luminescence and its temperature response behavior were explicated in detail before the attempt of further application. Such characteristic could generate three kinds of luminescence intensity ratio (LIR) to realize multimode temperature sensing, which owned higher accuracy compared to the single LIR technology. The relative sensitivity and repetition rate of the three modes were calculated, and the results were exceptional, indicating that the synthetic quasi-two-dimensional Y 2 O 3 : Bi 3+ , Sm 3+ nanosheet can prospectively be applied to multimode nano temperature sensing in the future.

“…The relative sensing sensitivity ( S r ) is also a significant parameter for thermometers, and it could be defined by the formula of

S_{r} = 100 % \times ((|, \frac{1}{FIR} \frac{d FIR}{dT})| = \frac{Δ E}{k T^{2}} \times 100 %

42,43 . Therefore, it is easy to estimate the S r values of the obtained samples.…”

As can be seen from Figure 11, the S r values of typical NCLVO:0.05Er 3+ , NSLVO:0.05Er 3+ , NCLVO:0.09Er 3+ , and NSLVO:0.09Er 3+ phosphors were found to be 1.15%, 1.18%, 1.11%, and 1.20% K −1 , respectively.…”

Novel green-emitting erbium(III) (Er 3+)-activated Na(Ca, Sr)La(VO 4) 2 phosphors with an interesting and stable trigonal structure were prepared. The crystal structure, elemental composition, morphology, photoluminescence, and sensing properties were investigated in detail. The color purity values of optimal NaSrLa(VO 4) 2 :0.05Er 3+ and NaCaLa(VO 4) 2 :0.05Er 3+ phosphors were calculated to be about 92.91% and 90.73% with the Commission Internationale de I'Eclairage color coordinates of (0.283, 0.684) and (0.295, 0.676), respectively. Meanwhile, the sensing property and cycling performance of those samples were also studied based on the thermalcouple levels of 4 S 3/2 and 2 H 11/2. The maximum absolute sensing sensitivity values of the NaCaLa(VO 4) 2 :Er 3+ and NaSrLa(VO 4) 2 :Er 3+ phosphors were found to be 9.23 × 10 −3 and 7.69 × 10 −3 K −1 while the relative sensing sensitivity values were found to be 1.15% and 1.20% K −1 , respectively. Furthermore, several repeated tests confirmed that the cycling performance was stable, demonstrating that the resultant samples with high and stable sensing sensitivity are great potential for optical thermometers.

“…In order to achieve accurate temperature measurement, strong upconversion emission and large temperature sensitivity are required. 12 Unfortunately, the thermal quenching of upconversion luminescence is universal, 13 which results in the quick decrease of signal-to-noise ratio and temperature measurement accuracy. It is urgently needed to seek optical temperature sensing materials with excellent performance.…”
