“…Hence, the X c is calculated to be 14.9, which is larger than 5, indicating that the electric multipole interactions are the main factors in generating the ET process of host → Eu 3+ in Ca 2 Sb 2 O 7 :Eu 3+ phosphors. Considering the electric multipole interactions are composed of three disparate kinds of types, the relationship between luminescence intensity and doping concentration is discussed based on the following expression η 0 η normals ∝ C n / 3 where η s and η 0 represent the energy-transfer efficiency of the host doped with and without the Eu 3+ ion, respectively. C is the doping content of Eu 3+ .…”

To date, non-contact luminescence thermometry methods based on fluorescence intensity ratio (FIR) technology have been studied extensively. However, designing phosphors with high relative sensitivity (S r) has become a research hotspot. In this work, Eu3+ single-doped Ca2Sb2O7:Eu3+ phosphors with a high S r value for dual-emitting-center luminescence thermometry are developed and proposed. The anti-thermal quenching behavior of Eu3+ originating from the energy transfer (ET) of host → Eu3+ is found and proved in the designed phosphors. Interestingly, adjustable color emission from blue to orange can be achieved. Surprisingly, the degree of the anti-thermal quenching behavior of Eu3+ gradually reduces from 240 to 127% as the Eu3+ doping content increases from 0.005 to 0.05 mol, attributed to most Eu3+ being located in the low symmetrical [Ca1O8] dodecahedral site. According to the differentiable responses of the host and Eu3+ to temperature, the maximal S r value reaches 3.369% K–1 (383 K). Moreover, the ambient temperature can be intuitively predicted by observing the emitting color. Owing to the excellent performance in optical thermometry, color-tunable properties, and outstanding acid and alkali resistance for polydimethylsiloxane (PDMS) films, the developed Eu3+ single-doped Ca2Sb2O7:Eu3+ phosphors are expected to be prospective candidates in luminescence thermometers and LED devices in various conditions.

“…Therefore, LNO: y Sm 3+ ( y = 0.001, 0.005) with a larger FIR value and stronger matrix emission than that of LNO: x Eu 3+ ( x = 0.001, 0.005) has a wider temperature measurement range. Furthermore, sensitivity is also a significant factor to evaluate temperature sensing performance, in which the absolute sensitivity ( S a ) and relative sensitivity ( S r ) could be expressed as follows: 40,41 …”

“…17,18 Therefore, in recent years, FIR based on non-TCELs (nTCELs) are preferred in the design of optical thermometers. 19 Multiple modes thermometry is a good strategy for increasing reliability and accuracy of temperature measurement. Multiple modes of thermometer can measure temperature simultaneously, achieving self-calibration of temperature measurement.…”

Multi‐mode optical thermometry is emerging as a promising technique for accurate temperature measurement. Here, a series of Na2GdMg2V3O12:Sm3+ (NGMVO:xSm3+) phosphors with dual‐emission centers were successfully elaborated. Irradiated by 349 nm light, NGMVO:Sm3+ can generate emissions from VO43− and Sm3+ simultaneously due to energy transfer between them. Benefitting from difference of thermal quenching performance of two luminescent centers, fluorescence intensity (FI), fluorescence intensity ratio (FIR), and Commission Internationale de L'Eclairage coordinate modes of NGMVO:Sm3+ thermometer were designed. Maximum relative sensitivities (SR) are found to be as high as 2.21 %K−1, 2.12 %K−1, and 0.244 %K−1, respectively. Besides, with temperature increasing, SR values of FI and FIR modes decrease slowly. Their minimal SR values between 303 and 513 K maintain above 1.36 %K−1 and 1.08 %K−1, respectively. Our findings reveal that NGMVO:Sm3+ phosphors have promising applications for multimode temperature senor.
