“…9, the two-step up-conversion of Ho 3+ and successive energy transfer from Yb 3+ to Ho 3+ are the main mechanisms of optical thermometry based on Ho 3+ doped phosphors. [60][61][62][63][64][65][66][67][68] In the case of a low doping concentration (<1%), the ESA process refers to a sequential absorption of two pump infrared photons at 890 nm by a single Ho 3+ ion. Upon 980 nm laser irradiation, Yb 3+ absorbs infrared photons with the generation of 2 F 7/2 / 2 F 5/2 upward transitions.…”

“…One formula is eqn (6), which is suitable to t DE f corresponding to transitions from 5 F 4 / 5 S 2 , 5 F 2,3 / 3 K 8 , and 5 G 6 / 5 F 1 to the 5 I 8 ground state. Using eqn (6) as a tting formula, the temperature dependent uorescence intensity ratios were studied in Ho 3+ doped TeO 2 glass and LiTeO 2 glass under 890 nm excitation, 62,63 and Ho 3+ -Yb 3+ co-doped CaMoO 4, CaWO 4 , and PbF 2 glass ceramic under 980 nm excitation. [66][67][68] A maximum S R of 0.098 K À1 for 130 K was obtained in Ho 3+ doped TeO 2 glass, and a maximum S A of 2191.9/T 2 was obtained in Ho 3+ -Yb 3+ co-doped glass ceramic.…”

We studied the temperature dependence of the up-conversion emission in the green and the red regions of the electromagnetic spectrum of Ho,Yb:KLu(WO 4 ) 2 nanocrystals after excitation at 980 nm, and analyzed their possible applications as thermal sensors in luminescence thermometry in the RT to 673 K range, by using different techniques. The different thermometric techniques used arethe fluorescence intensity ratio technique of two thermally coupled Stark sublevels, the intensity ratio between the red and green luminescence bands generated by two electronically and thermally linked manifolds of these nanoparticles, lifetime measurements, or by observing the change of the color of the emitted light arising from the sample. In all cases, thermal sensitivities comparable to those previously reported in the literature are obtained, but offering different thermal sensing approaches using a single material, providing a way to corroborate the temperature measurements.

“…FIR‐based optical media temperature sensors require two emission peaks, and the response to the temperature stimulus must be different 2 . At present, lanthanide (Ln 3+ ) activators are widely used as temperature probes in many system of luminescent materials such as NaLuF 4 :Yb 3+ /Ho 3+ , 13 TeO 2 :Yb 3+ /Ho 3+ , 14 P 2 O 5 ‐ZnO‐Na 2 O:Yb 3+ /Er 3+ , 15 TeO 2 ‐Li 2 CO 3 :Pr 3+ , 7 Ba 5 Gd 8 Zn 4 O 21 :Yb 3+ /Tm 3+ , 16 Ca 5 (PO 4 ) 3 F:Yb 3+ /Er 3+ , 17 etc…”

In this paper, the Yb 3+ /Er 3+ co-doped parent glass (PG) with composition (in mol%) of 30P 2 O 5-10B 2 O 3-38SrO-22K 2 O and transparent glass-ceramics (GCs) containing hexagonal Sr 10 (PO 4) 6 O nanocrystals (NCs) were synthesized for the first time by melt-quenching method and subsequent heating treatment in air. Under 980 nm laser prompting, the GCs samples showed intense red and green up-conversion emissions compared to those characteristics for the PG sample. The emission intensities varied with Er 3+ concentration and heat treatment conditions. Furthermore, in Yb 3+ /Er 3+ co-doped GCs specimens, the optical thermometry was researched by means of fluorescence intensity ratio (FIR) of 4 S 3/2 and 2 H 11/2 levels. The GC sample heated at 620°C for 5 hours possessed a high relative temperature sensitivity (S r) of 0.769% K −1 at 303 K and the maximal absolute temperature sensitivity (S a) of 5.951 × 10 −3 K −1 at 663 K, respectively. It is expected that the as-fabricated GC materials with Sr 10 (PO 4) 6 O NCs are promising efficient up-conversion materials for optical temperature sensor.
