Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Up conversion luminescent materials Sr 2 YTaO 6 : Er 3+, Yb 3+ phosphors were prepared by high temperature calcination. In view of the formation, temperature characteristics, and photoluminescence features of the sample, X-ray diffraction and photoluminescence were used. Under the excitation at 980 nm, the series of samples is significantly stimulated by Er 3+ up-conversion luminescence and Yb 3+ sensitization at 524, 550 and 659 nm. According to the diversity of temperature sensing performance from these three highest peaks, a dual-mode temperature sensor on account of fluorescence intensity ratio (thermally coupled level between 2 H 11/2 and 4 S 3/2, and nonthermally coupled energy levels between 2 H 11/2 and 4 F 9/2 ) is achieved by using a single luminescent center. Moreover, the phosphor has strong thermal stability, which is helpful to improve the accuracy of temperature measurement. Under the temperature measurement of a dual-mode temperature sensor, it is calculated that the optimal absolute sensitivity S a of thermally coupled energy level is 0.78 × 10 −3 K −1 (473 K) and relative sensitivity S r is 1.32 %K −1 (293 K), and the maximum optimal absolute sensitivity S a of non-thermally coupled energy level is 1.02 × 10 −4 K −1 (473 K) and relative sensitivity S r is 0.58 %K −1 (293 K). All results imply that Sr 2 YTaO 6 : Er 3+, Yb 3+ phosphors are promising materials for self-referenced optical temperature measurement.
