Excellent multi-color emission and multi-mode optical ratiometric thermometer in (Ca, Tb, Eu, Sm)Nb2O6 phosphors based on wide O2–→Nb5+ CTB

Slow magnetic relaxation in Nd(iii) and Sm(iii) complexes formed in three-dimensional lanthanide-dicyanidometallate(i) frameworks exhibiting luminescent properties

“…The observed sensitivity values are similar to those of other Ln-containing molecular compounds. 69,70…”

“…The observed sensitivity values are similar to those of other Lncontaining molecular compounds. 69,70 This is also the first example of Sm(III) possessing a molecule-based compound exhibiting ratiometric and thermometric properties that can be synthesized easily in the lab. A few studies have reported ratiometric thermometers for Sm(III) comprising phosphors.…”

“…A few studies have reported ratiometric thermometers for Sm(III) comprising phosphors. [69][70][71][72] Table 3 compares the reported sensitivities. SmAu in the broad T-range has good thermometric performance in comparison to other systems (Table 3) and a particularly good S r value for the low-temperature range.…”

Lanthanide-doped lead-free double perovskite La2MgTiO6 as ultra-bright multicolour LEDs and novel self-calibrating partition optical thermometer

“…8b clearly show that LIR 1 Tm is highly fitted to eqn (5). According to previous reports, in order to facilitate the evaluation of the heat sensing performance of the synthesized materials, two important parameters, absolute sensitivity ( S a ) and relative sensitivity ( S r ), are usually introduced to accurately compare the thermal sensitivity properties between different thermometers, which can be calculated as shown below: 47,48 …”

Measurement of transient temperature using laser-induced breakdown spectroscopy (LIBS) with the surface temperature effect

“…[1][2][3][4][5] While many successful temperature measurement methods have been developed, measuring temperature under extreme conditions remains a challenge. [6][7][8][9][10][11][12][13][14] For example, acquiring the transient surface temperature of a linear electromagnetic propulsion slide rail or gun barrel is difficult because the temperature increases abruptly in several hundred microseconds due to high-speed sliding. [15][16][17][18][19] Therefore, the time resolution of the transient surface temperature measurement needs to reach at least the microsecond level, and even the nanosecond level to reveal the phase explosion of the high-speed friction erosion process.…”
