“…The results suggest that the FIR values exhibit a high degree of repeatability. Measurement error (∆ T ) is an important indicator for evaluating the accuracy of a thermometer, and it can be expressed by the following formula: [ 29 ]

\begin{equation}\Delta T = \frac{1}{{{S}_r}}\frac{{\Delta R}}{R}\end{equation}

where ∆ R / R denotes the standard deviation in the measurement of the temperature parameter. The standard deviation is calculated to be 1.84% based on the measured data of the thermal cycling process.…”

The realization of dual‐wavelength Mn2+ upconversion (UC) luminescence that exhibits different thermal responsive behaviors is promising for non‐invasive optical temperature sensing applications. However, it remains challenging to achieve such luminescence of Mn2+ ions. Herein, due to the site preference characteristics of Mn2+, color tunable and dual‐wavelength Mn2+ UC luminescence is achieved in K2NaScF6:Yb3+, Mn2+ by simply adjusting the Mn2+ doping concentration. Structural and spectral analysis as well as theoretical calculations reveal that the green and red UC emissions originate from two kinds of face‐sharing Yb3+‐Mn2+ dimers, which exhibit different luminescence properties, including different emission wavelength, excited state lifetime, full width at half maximum (FWHM), and luminescence thermal stability. This unique dual‐wavelength UC luminescence of Mn2+ provides a new type of fluorescence intensity ratio thermometer with absolute and relative sensitivities of up to 0.018 K−1 and 0.525% K−1, respectively. This work not only demonstrates the potential application of K2NaScF6:Yb3+, Mn2+ material in the field of optical thermometry but also provides new perspectives for designing multi‐band Mn2+ UC luminescence.

“…As a popular research temperature measurement device in recent years, the non-contact optical temperature sensor, with good accuracy and resolution, has broken through the spatial limitations and is expected to be the next generation of temperature sensing technology. [5][6][7] Currently, the research on non-contact optical temperature sensors has focused on the use of optical parameters such as single fluorescence intensity, fluorescence intensity ratio (FIR), emission bandwidth, peak wavelength, and fluorescence life-time to detect temperature. 8 Among them, FIR techniques based on two thermally coupled energy levels have been extensively studied in the field of non-contact optical temperature measurement.…”

method, [9] electrochemical method, [10] fluorescence spectrometry, [11] photothermal effect method, [12] anodic dissolution voltammetry, [13] and surface plasmon resonance method. [14] However, colorimetric and photothermal methods require a lot of chemical reagents such as Amino-Functionalized Au@G NPs and Chloroauric acid, [9,12] which can easily cause environmental pollution. Both the anodic dissolution voltammetry and surface plasmon resonance methods are expensive because they require the consumption of a certain number of precious metals such as gold. [13,14] Many other ways of fluorescence spectroscopy, photothermal effect, and anodic dissolution voltammetry are complex, longer consuming time, and inconvenient inspection. [11][12][13] Optic-fiber sensors can be made with large bandwidth, low cost, lightweight, anti-electromagnetic interference, chemical inertness, easy to realize multi-band, and remote real-time monitoring capability, which have been widely used for temperature, [15] humidity, [16] refractive index, [17] gas concentration, [18] breath detection [19] and metal ion detection. [20] So far, many fiber optic sensing techniques for detecting metal ions have been proposed, and the main detection methods are intensity detection, [15][16][17]21] plasma, [22] fluorescence effect, [23] and interference wavelength detection. [24] The main trends are the preparation of sensitizing coatings, the use of vernier effects, and the preparation of micron structures. [20] Many structures of optic fiber are suitable for metal ion detection such as Bragg grating, [24] D-shaped fiber, [25] tilted fiber Bragg grating [26] , and microfiber. [27] Among them, optic-microfibers offering the possibility of strong evanescent fields out of fiber cladding for high-sensitive measurement provide a new option to explore more efficient and economical ion concentration sensing applications.In this paper, we present a microfiber interferometer sensor based on a ternary one-piece sensitive film (PVA-APTES-ICA (PVA, Poly(vinyl alcohol); APTES, (3-Aminopropyl)triethoxysilane; ICA, Imidazole-2-carboxaldehyde)) for the detection of copper ion concentration. The sensing structure can effectively enhance the detection capability of copper ions with a sensitivity of up to 7.715 × 10 6 nm M −1 and the detection limit of 0.0576 ppm in the concentration range of 100 to 1000 nM. The sensor has insensitive to temperature with a sensitivity as low as −0.007 nm °C−1 , which can ignore the temperature cross-influence. The sensor simplifies the manufacturing process of traditional sensors. Stability and anti-interference experiments demonstrated the longterm stability and good specificity of the sensor, which has good application prospects.An optic-fiber sensor for detecting the concentration of trace copper ions is proposed using a ternary cross-linked sensitive film coated on the Mach-Zehnder microfiber interferometer surface. The microfiber has a huge evanescent field offering high sensitivity to the ambient refractive index. The chelation...
