Ho,Yb:KLu(WO4)2 Nanoparticles: A Versatile Material for Multiple Thermal Sensing Purposes by Luminescent Thermometry

“…However, in the latter case, the synthesis procedure was complex, the temperature range explored was very narrow, and it was not indicated at which wavelength the quantum dots/organic dye system was pumped. 76 Also Eu-doped SiO 2 submicrometric spheres exhibit a higher sensitivity in a shorter temperature range, 13 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 these systems operated in the green region of the electromagnetic spectrum.

Er:Yb:NaY2F5O up-converting nanoparticles for sub-tissue fluorescence lifetime thermal sensing

“…9-13 Among the different systems proposed until now for LNT, nanomaterials doped with lanthanide ions play an important role, due to their intrinsic advantages such as relatively large uorescence lifetimes, good chemical and physical stabilities, narrow emission lines and so on. [14][15][16][17][18][19] Among the different LNT modalities, lifetime based LNT (hereaer LT-LNT) is of spectral relevance. LT-LNT is said to be used when the temperature of the nanoprobe is estimated from the analysis of its uorescence lifetime that, consequently, should be strongly temperature dependent.…”

Avoiding induced heating in optical trap

“…Although we were able to detect several emission bands generated by Er 3+ ions, in the following we will focus our attention on those bands lying within the 500-570 nm spectral range, as they are known to be especially sensitive to temperature changes. [1][2][3][14][15][16][17] In particular, as it can be observed in Figure 1(d Figure 1(c)). As these emission bands are generated from two thermally coupled excited states ( 2 H sensing.…”
