“…Figure 1 shows a simplified energy level diagram of the green up-conversion emissions for the Er 3+ doped silicate glass by a 978 nm LD excitation [15,16]. The excited state absorption (ESA) of 4 I 11/2 +a photon→ 4 F 7/2 and cross-relaxation (CR) of 4 I 11/2 + 4 I 11/2 → 4 I 15/2 + 4 F 7/2 populate the Er 3+ on 4 F 7/2 level by following the ground state absorption (GSA) of 4 I 15/2 +a photon→ 4 I 11/2 , and a nonradiative decay from 4 F 7/2 to 2 H 11/2 and 4 S 3/2 levels produce the final green up-conversion emissions population of Er 3+ .…”

The green up-conversion emissions centered at the wavelengths of about 534nm and 549nm of the Er3+ doped silicate glass were recorded, using a 978 nm semiconductor laser diode (LD) as an excitation source. The fluorescence intensity ratio (FIR) of the green up-conversion emissions at about 534nm and 549nm in the Er3+ doped silicate glass was studied as a function of temperature over the temperature range of 296K-673K. The maximum sensitivity and the temperature resolution derived from the FIR of the green up-conversion emissions are approximately 0.0023K-1 and 0.8K, respectively. It is demonstrated that the prototype optical temperature sensor based on the FIR technique from the green up-conversion emissions in the Er3+ doped silicate glass could play a major role in temperature measurement.

“…There is an obvious crystallization peak at 385˚C (Tx). The difference between the glass transition temperature (Tg) and the onset crystallization temperature (Tx), ΔT = Tx -Tg has been frequently quoted as a rough indicator of glass stability against crystallization [14][15][16]. It is desirable for a glass host to have a ΔT as large as possible.…”

A series of Er 3+ /Yb 3+ co-doped Sb 2 O 3-WO 3-Li 2 O glasses were prepared. Intense green upconversion fluorescence was observed near 524 and 544 nm under excitation at 980 nm. The upconversion process was proved to be a two-photon absorption process. The upconversion fluorescence efficiency was enhanced by increasing introduction concentration of Yb 3+ ions. The low maximum phonon energy of the glasses indicated that the glasses were good potential for upconversion optical devices.

“…This latter family of glasses is characterized by a low phonon energy (700 cm -1 ≤ E p < 800 cm -1 ), a good chemical durability, especially in liquid water and mechanical properties. Up-conversion has been studied in multicomponent glasses based on the oxides of Te , Ge , Bi and Pb as major components stabilized by oxides of Zn , Ga , W and Nb [33][34][35][36]. Sb 2 O 3 contributes in the glass network with SbO 3 structural units and it appears tetrahedra with the oxygens to be found at three corners and the lone pair of electrons of antimony Sb 3+ at the fourth corner localized in the third equatorial direction of the Sb atom.…”

The up-conversion emission of Nd 3+ , Sm 3+ and Er 3+ has been studied in a new halogenoantimonite glass with the chemical composition 80 Sb 2 O 3 -10 ZnBr 2 -10 KCl. Doping concentration was 0.2 mol% of lanthanide (Ln) ions. Rare earths were introduced as fluorides LnF 3 that were further converted into oxides. Main physical properties of base glass were measured, including density, thermal expansion, characteristic temperatures, refractive index and optical transmission. The amount of residual hydroxyls was calculated from the OH absorption band around 3000 nm. The recorded up-conversion emission lines are λ em = 536 nm for Nd 3+ pumped at 805 nm; λ em = 563 nm, 600 nm, 631 nm and 645 nm for Sm 3+ pumped at 945 nm; λ em = 531 nm for Er 3+ pumped at 798 nm. Co-doped glass (0.1 Yb 3+ + 0.1 Er 3+ ) pumped at 980 nm has three emission lines at 524 nm, 545 nm and 650 nm. Corresponding transitions have been identified and the mechanisms ruling the up-conversion process is discussed. They include excited state absorption (ESA), energy transfer (ET) cooperative energy transfer (CET), emission assisted by phonon (EAP), multiphonon relaxation (MR) and cross-relaxation (CR).
