Luminescent thermometry (LT) is a technique that enables contactless temperature determination based on temperature dependent luminescence of phosphors. Among different LTs that have been described in the literature so far, the luminescence intensity ratio (LIR) based thermometers have shown the highest application potential. Nevertheless, to determine accurate temperature, ratiometric method encounters technical restrictions related to the need for spectral separation of temperature dependent emission bands. An alternative ratiometric approach can exploit the intensity of a single emission band being excited in two ways related to ground state absorption (GSA) and excited state absorption (ESA). In this work, this approach, i.e., luminescent thermometry involving ESA process in LaPO4:Nd3+ nanocrystals, was demonstrated. Thermal energy delivered to the system was responsible for partial population of Nd3+:4I11/2 level, which enabled non-GSA-absorption of 1060 nm excitation line and resulted in appearance of strongly temperature dependent emission band at 890 nm. The further temperature increase favored population of higher laying levels, resulting in observation of 810 and 750 nm emission. On the other hand, the intensity of the emission band at 890 nm being excited in a resonant GSA way via the 808 nm line was strong and barely dependent on temperature, thus serving as a reference. Therefore, three luminescence intensity ratio (LIR i ) equations were defined to determine temperature in a contactless way. The subsequent LIRs were calculated as the ratios of emission intensities at 890, 810, and 750 nm being excited in a non-GSA-resonant ESA-resonant way normalized to the band at 890 nm excited with 808 nm line (through GSA). The highest relative sensitivities were unprecedentedly high and reached S 1 = 7.19%/°C at 30 °C, S 2 = 3.04%/°C at 100 °C, and S 3 = 4.35%/°C at 180 °C for the subsequent LIR i ratios.

“…The FT-IR spectrum of the NaYF 4 :Yb,Er clusters shows that the characteristic absorption peaks are the same as the PAAS raw material, and the characteristic absorption peaks at 3440, 2934, 2359 and 1570 cm À1 can be attributed to the stretching vibration of O-H groups, the stretching vibration of aromatic C-H in-plane, and the stretching vibration of -COO À groups, respectively. 23 The absorption peaks of the calcinated NaYF 4 : Yb,Er clusters at 2934, 2359, and 1570 cm À1 are eliminated, which further confirms the removal of PAAS after calcination. The TGA curve can be obtained by thermal gravimetric analysis as shown in Fig.…”

Highly sensitive non-contact mode temperature sensing is substantial for studying fundamental chemical reactions, biological processes, and applications in medical diagnostics. Nanoscale-based thermometers are guaranteeing non-invasive probes for sensitive and precise temperature sensing with subcellular resolution. Fluorescence-based temperature sensors have shown great capacity since they operate as “non-contact” mode and offer the dual functions of cellular imaging and sensing the temperature at the molecular level. Advancements in nanomaterials and nanotechnology have led to the development of novel sensors, such as nanothermometers (novel temperature-sensing materials with a high spatial resolution at the nanoscale). Such nanothermometers have been developed using different platforms such as fluorescent proteins, organic compounds, metal nanoparticles, rare-earth-doped nanoparticles, and semiconductor quantum dots. Carbon dots (CDs) have attracted interest in many research fields because of outstanding properties such as strong fluorescence, photobleaching resistance, chemical stability, low-cost precursors, low toxicity, and biocompatibility. Recent reports showed the thermal-sensing behavior of some CDs that make them an alternative to other nanomaterials-based thermometers. This kind of luminescent-based thermometer is promising for nanocavity temperature sensing and thermal mapping to grasp a better understanding of biological processes. With CDs still in its early stages as nanoscale-based material for thermal sensing, in this review, we provide a comprehensive understanding of this novel nanothermometer, methods of functionalization to enhance thermal sensitivity and resolution, and mechanism of the thermal sensing behavior.
