Abstract

Near-infrared (NIR)-emitting Yb3+-containing glasses with 50P2O5-(50 – x)BaO-xYb2O3 (x = 0, 0.5, 1.0, 2.0, 3.0, 4.0 mol %) nominal compositions were made by melting and studied comprehensively through refractive index, density, X-ray diffraction, X-ray photoelectron spectroscopy, Raman spectroscopy, dilatometry, differential scanning calorimetry, UV–Vis-NIR optical absorption, and photoluminescence spectroscopy measurements. The results obtained from the various techniques were analyzed quantitatively in detail and discussed in the context of the variation in Yb2O3 contents and the impact of high-field strength Yb3+ ions affecting the different properties. Ultimately, concentration correlations with data obtained from densitometry, Raman scattering, dilatometry, calorimetry, and photoluminescence measurements pointed to the occurrence of a critical Yb2O3 concentration at about 1.9 (± 0.3) mol% distinguishing low- and high-concentration effects of Yb3+ ions.
