“…Regarding the effects on A375 cells, the nanoparticles did not affect the cell viability at 24 h but induced a decrease in cell viability for the highest concentrations (87.7±## % for 100 µg•mL −1 and 82.5±## %% for 200 µg•mL −1 ) after 48 h. Nevertheless, the viability of both cell lines is above the 70% threshold [43] and the (Gd0.97Yb0.02Er0.01)2O3 nanoparticles can be considered non-cytotoxic, at the range of tested concentrations. These results concur with our previous study with the exposure of (Gd0.98Nd0.02)2O3 nanoparticles to MNT-1 cells, which did not induce toxicity by 24 h exposure for concentrations up to 400 µg•mL −1 [44]. The blue rectangle shown in Figure 5 is magnified in Figure 6a corresponding to the selected area to study the internalization and localization of the Yb 3+ /Er 3+ -codoped Gd3O2 nanoparticles combining 2D optical and hyperspectral images.…”

“…Luminescent nanothermometry , has become a well-established field in recent years, gradually gaining popularity not only in the study of temperature sensors but also in research devoted to luminescence processes in general. Novel nanomaterials and methods of optical noncontact temperature readout in demanding or harsh conditions (such as biologically relevant media and variable pH or viscosity) are being increasingly developed. − A significant advantage of some of the proposed luminescent thermometers is their nanometric size because it enables application in the most challenging fields such as bioimaging, medical diagnostics, and microelectronics. Innovative application possibilities are investigated, and increasingly advanced results are presented in these fields. − However, in order to maintain the growth rate of luminescent thermometry popularity, not only material research but also methods to verify the theory of thermal phenomena occurring in nanothermometers should be developed.…”

One of the challenges currently facing luminescent thermometry is providing an in-depth analysis of thermally dependent processes occurring in the studied type of nanothermometer. By understanding all possible thermal phenomena, the properties of a given kind of nanosensor can be intentionally improved. Verification of the existing theories on a nanometric scale is particularly important. In this work, a comprehensive characterization of the structural and optical properties of nanocrystalline KLaP4O12 doped with different concentrations of Tb3+ ions was performed. It was shown that Tb3+ ions excited using two distinct wavelengths matched to the ground- and excited-state absorption show luminescences of opposite thermal dependencies. This enabled the single-band-ratiometric (SBR) thermometric approach to be implemented. The experimentally obtained results turned out to be consistent with the proposed form of state equations describing the dynamics of populating Tb3+ energy levels as a function of the temperature. As reported here, the first SBR nanothermometer based on Tb3+ ion emission stands out because of its nanometric size and high relative sensitivity, reaching 5%/°C at 0 °C. Finally, on the basis of modeling changes in the individual parameters in the state equations, their impact on the results obtained for SBR thermometers based on Tb3+ ions was widely discussed.

Temperature has a significant impact on the luminescence profile of photonic materials for biological applications. This paper presents the effect of temperature on the luminescence profile of three different photonic materials in the range of the second biological window. The effect of temperature on luminescence properties is shown on glass, glass-ceramics, and phosphors co-doped with Eu3+/Nd3+/Yb3+ under UV laser diode excitation. Each sample has been analyzed for temperature effects on optical parameters in biological window ranges. Moreover the effect of temperature on mechanisms of energy transfer Eu3+ → Nd3+ → Yb3+ in all fabricated photonic materials was analyzed. Full Text: PDF References J. Zhou, J.L. Leano Jr., Z. Liu, D.
