“…5a for three concentrations of Er 2 O 3 . The used 1064 nm radiation cannot excite the upper levels of the Er 3+ ion but only the 4 I 13/2 one, i.e., the obtained PL is due to the 4 I 13/2 – 4 I 15/2 transition 38. Every precaution has been taken to preserve the optical geometry of the PL setup during measurements of the three samples, so that quantitative comparison of PL spectra could be made.…”

“…The PL spectra of the strong emission band at $1530 nm of studied glasses are measured at room temperature under direct excitation of Er 3þ ions (l exc ¼ 1064 nm) and are presented in Fig. 5a [38]. Every precaution has been taken to preserve the optical geometry of the PL setup during measurements of the three samples, so that quantitative comparison of PL spectra could be made.…”

International audienceHighly stable glasses in the (70 − x)Sb2O3[BOND]20Na2O[BOND]10ZnO[BOND]xEr2O3 (x = 0.25, 0.5, and 1.0 mol%) system have been prepared and investigated by UV-Vis-NIR absorption, near infrared photoluminescence and time-resolved spectroscopy. Judd-Ofelt study has been used to determine the intensity parameters (Ω2, Ω4, and Ω6), spontaneous emission probabilities, branching ratios, and radiative lifetimes (τR) related to the corresponding optical transitions of Er3+ ions. Details of the emission at ∼1530 nm and spectroscopic characteristics such as the stimulated emission cross-section (σe), effectiveband width (Δλeff), quantum efficiency, and the optical gain have been summarized, accounting the role of the increased Er content. The obtained results indicate that these new low phonon energy glasses could be used as a laser medium and for optical amplification in the 1.5 µm region. In particular, the composition containing 0.5 mol% Er2O3 exhibits optimal values of Ω2 (4.5 × 10−20 cm2), Δλeff = 57 nm, σe = 7.28 × 10−21 cm2, τmeas (3.36 ms), and quantum efficiency of the 4I13/2 level of Er3+ ions ∼71%

“…Very little research has been conducted on the strengthening of non-silicate glass, especially on Er-doped phosphate glass. Due to the transition of Er 3+ from 4 I 13/2 → 4 I 15/2 , corresponding to the wavelength of maximum transparency of standard silica-based optical fibres, Er 3+ doped material has played an important role in the development of optical communication technology [7,8]. Furthermore, rare earth doped phosphate glasses are the preferential material for use in high energy and high peak power laser systems [9].…”

Two kinds of Er-doped lithium phosphate glass have been chemically strengthened by ion exchange in a mixed binary melt of KNO3 and NaNO3 at temperature far below glass Tg. Ion depth profile has been determined with WDS technique. The effect of acid wash on surface morphology, hardness and fracture temperature of glass was investigated. It was found that acid wash following ion exchange could improve the surface morphology and strength of glass. Nevertheless, WDS analysis showed that the acid wash could cause the ion diffusion from glass surface to acid wash liquid, i.e. the back diffusion of K+ and Na+. The results revealed that the back diffusion of K+ was severer than that of Na+ during acid wash and the bond of K+ to glass network was weak.
