“…Table 2 displays the maximum relative thermal sensitivity of several luminescence thermometers that are single-doped with rare earth elements. As shown in this table, the value obtained here of 0.10% K −1 is higher than that reported in the literature for other systems based on the FIR method: 0.016% K −1 at 300 K for Sm 3+ :SrWO4 [27], and 0.018%K −1 at 640 K for Sm 3+ :Flurotellurite [4], although it is lower than the value of 0.36%K −1 at 466 K for Sm 3+ :YVO4 [38].…”

“…One important example of optical temperature sensing systems is those based on trivalent rare earth (RE 3+ ), such as Eu 3+ , Er 3+ , and Dy 3+ [23][24][25][26]. These ions can be incorporated into a variety of materials, including phosphors [23,27], polymers [28,29], and glasses [4,30,31]. Commonly, a relative thermal sensitivity of 0.5%-2.0%K −1 can be achieved in these systems [22,32,33].…”

This study reports the synthesis and characterization of glasses in the (100-x) 65TeO2-15Li2O-20ZnO + x Sm2O3 system doped with Sm2O3, denoted as Sm3+: TLZ glasses, with varying doping concentrations from 0.1, 0.15, 0.2, 0.35, 0.5, and 1 mol%. The structural and optical properties, as well as the temperature dependence of luminescence, were investigated. Excitation at 405 nm resulted in strong orange-red luminescence at 566, 600, and 646 nm. The local environment surrounding Sm3+ ions was explored using the intensity ratio of electric and magnetic dipole transitions. The non-radiative energy transfer between neighboring Sm3+ ions was evaluated using the Inokuti-Hirayama model, allowing for the determination of the critical transfer distance. The temperature dependence of luminescence, displayed by Commission Internationale de L'Eclairage (CIE) chromaticity coordinates, exhibited a monotonic change from (0.611, 0.387) at 295 K to (0.605, 0.393) at 479 K. The Sm3+:TLZ glasses doped with 0.15 mol% showed the highest relative thermal sensitivity of 0.10%K-1 at 479 K, suggesting their potential as luminescent thermometers.

“…The ratio of intensities, which is dependent on temperature, remains unaffected by the intensity of the source, as the emitted intensities are directly proportional to the population of the respective energy levels. Thus, the ratio of fluorescence intensity denoted as I between two energy levels that are thermally linked can be expressed as [42, 43]:

FIR goodbreak= I goodbreak= A e^{\frac{- ∆ E}{italickT}}

where A is a constant, ∆ E is the energy difference between two excited levels, and k is the Boltzmann constant ( k = 0.695 cm −1 K −1 ).…”

The present study investigates the impact of the ligand environment on the luminescence and thermometric behavior of Sm3+ doped A3(PO4)2 (A = Sr, Ca) phosphors prepared by combustion synthesis. The structural and luminescent properties of Sm3+ ions in the phosphate lattices were investigated using powder X‐ray diffraction (PXRD) and photoluminescence (PL) techniques. PXRD results of the synthesized phosphors exhibit the expected phases that are in agreement with their respective standards. Fourier‐transform infrared (FTIR) spectroscopy confirms the presence of PO4 vibrational bands. Upon excitation with near ultraviolet light, the PL studies indicated that Sr3(PO4)2:Sm3+ phosphors exhibit a yellow light emission, whereas Ca3(PO4)2:Sm3+ phosphors exhibit an emission of orange light. The PL emission results are in accordance with the CIE coordinates, with the Sr3(PO4)2:Sm3+ phosphors showing coordinates of (0.56, 0.44), and the Ca3(PO4)2:Sm3+ phosphors displaying coordinates of (0.60, 0.40). Thermal analysis shows improved stability of Ca3(PO4)2:Sm3+ based on lower weight reduction in thermogravimetric analysis. The effect of temperature on the luminescence properties of the phosphor has been examined upon a 405 nm excitation. By using the fluorescence intensity ratio (FIR) method, the temperature responses of the emission ratios from the Sm3+: the 4F3/2 → 6H5/2 transition to the 4G5/2 → 6H7/2 and 4F3/2 → 6H5/2 transition to the 4G5/2 → 6H9/2 emissions are characterized. The Ca3(PO4)2:Sm3+ phosphors are more sensitive as compared with the Sr3(PO4)2:Sm3+ phosphors. The earlier research findings strongly indicate that these phosphors hold great promise as ideal candidates for applications in non‐invasive optical thermometry and solid‐state lighting devices.

“…17 For Sm 3+ doped SrWO 4 phosphor and Nd 3+ /Yb 3+ co-doped SrWO 4 phosphor, they also have good temperature sensing performance. 18,19 Note that, the SrWO 4 material is more suitable to be a UC uorescence host for designing optical temperature sensor. However, as far as we know, the SrWO 4 :Yb 3+ /Ho 3+ phosphor for optical thermometry has not been investigated.…”
