“…For example, Li et al 44. and Feng et al 4950515253. used Er 3+ /Yb 3+ co-doped silicate-based glass with high Yb 3+ concentrations, which reduced the energy transfer efficiency owing to the high phonon energy of these glass hosts, lowering the thermal sensitivity of their materials.…”

The determination of temperature is essential in many applications in the biomedical, technological, and industrial fields. Optical thermometry appears to be an excellent alternative for conventional electric temperature sensors because it is a non-contact method that offers a fast response, electromagnetic passivity, and high temperature sensitivity. In this paper, we propose an optical thermometer probe comprising an Er3+/Yb3+ co-doped tellurite glass attached to the tip of an optical fibre and optically coupled to a laser source and a portable USB spectrometer. The ratio of the up-conversion green emission integrated peak areas when excited at 980 nm was temperature dependent, and it was used to calibrate the thermometer. The thermometer was operated in the range of 5–50 °C and 50–200 °C, and it revealed excellent linearity (r2 > 0.99), suitable accuracy, and precisions of ±0.5 and ±1.1 °C, respectively. By optimizing Er3+ concentration, we could obtain the high green emission intensity, and in turn, high thermal sensitivity for the probe. The probe fabricated in the study exhibited suitable properties for its application as a temperature sensor and superior performance compared to other Er3+ -based optical thermometers in terms of thermal sensitivity.

An ultrabroadband near-infrared (NIR) emission of Ni 2+ is demonstrated in a highly transparent nano-glass ceramic (nano-GC) containing Ga 2 O 3 nanocrystals with 808 nm excitation of Nd 3+. It is also shown that by adding Yb 3+ as an energy transfer (ET) bridge, the Ni 2+ emission could be substantially enhanced. The dopant distribution was studied using advanced analytical transmission electron microscopy. This, together with optical transmission measurements, steady-state and time-resolved emission spectra, is utilized to understand the underlying ET mechanisms between Nd 3+ , Yb 3+ , and Ni 2+. The feasibility of this device as a viable source is demonstrated using dual-laser pumping at 808 and 980 nm for the greatest Ni 2+ emission enhancement reported to date. The Nd 3+ /Yb 3+ /Ni 2+ triply doped nano-GC offers a promising gain medium for broadband and tunable NIR fiber amplifiers.

Enhanced 2.0 μm and visible up‐conversion emissions from Ho3+ via Yb3+ sensitization in lead silicate glasses have been obtained under the excitation of 980‐nm laser diode. The possible energy transfer mechanism has been analyzed based on the photoemission spectroscopy and lifetime measurement. The lifetime of Ho3+: 5I7 laser upper level has also been measured. Based on the absorption spectra, Judd–Ofelt parameters, spontaneous emission probability, the absorption, emission cross sections, and gain coefficients have been calculated and analyzed. The results indicate that the Yb3+/Ho3+ co‐doped lead silicate glass has potential application in mid‐infrared wavelengths.
