“…Thus, incorporation of Ag as metallic NPs in glass matrix changed the ligand field of Er 3+ . As seen in Table 4, the X 2 intensity parameter in our samples is larger than those of NZLE0 phosphate [25] TZNE1 tellurite [26], and NPP30 Chlorophosphate [27] glasses. This feature reflect the asymmetry of the local environment at the Er 3+ ion site and exhibits the dependence on the covalency between rare earth ions and ligand anions [28].…”

“…The values of emission and absorption cross-sections were calculated and listed in Table 7. We find that the emission cross r e relative to NPZEA0 is larger than that of TZNE1 [26], Bismuth [44] and Aluminosilicate [45] glasses, which indicates that the NPZEA0 sample glass is a favorable material for optical amplifiers.…”

“…It can be seen from Table 2 that the value of Ω 2 decreases with the increase of heat-treated temperature confirming the incorporation of Er 3+ into the precipitated nanocrystals. In addition, the value of Ω 6 , which is proportional to the rigidity of the host, increases slightly in the transition from glass to GCs29.…”

Transparent Er3+-doped germanotellurite glass ceramics (GCs) with variable Te/Ge ratio were prepared by controllable heat-treated process. X-ray diffraction (XRD) and transmission electron microscope (TEM) confirmed the formation of nanocrystals in glass matrix. Raman spectra were used to investigate the evolution of glass structure and photon energy. Fourier transform infrared (FTIR) spectra were introduced to characterize the change of hydroxyl group (OH−) content. Enhanced 2.7 μm emission was achieved from Er3+-doped GCs upon excitation with a 980 nm laser diode (LD), and the influence of GeO2 concentration and heat-treated temperature on the spectroscopic properties were also discussed in detail. It is found that the present Er3+-doped GC possesses large stimulated emission cross section at around 2.7 μm (0.85 × 10−20 cm2). The advantageous spectroscopic characteristics suggest that the obtained GC may be a promising material for mid-infrared fiber lasers.

“…4 I 15/2 transition in prepared glasses and confirms the mechanism of energy transfer from silver NPs to Er 3þ ions. We find that the emission cross r e relative to TABNE10 is much larger than those of the silicate, 43 germinate, 44 tellurite, 34 and phosphate 37 glasses. The full-width at half-maximum (FWHM) was also calculated and listed in Table V.…”

Articles you may be interested inEnergy transfer characteristics of silicate glass doped with Er3+, Tm3+, and Ho3+ for 2μm emission Tellurite glasses doped Er 3þ ions and containing Silver nanoparticles (Ag NPs) are prepared using melt quenching technique. The nucleation and growth of Ag NPs were controlled by a thermal annealing process. The X-ray diffraction pattern shows no sharp peak indicating an amorphous nature of the glasses. The presence of Ag NPs is confirmed from transmission electron microscopy micrograph. Absorption spectra show typical surface plasmon resonance (SPR) band of Ag NPs within the 510-550 nm range in addition to the distinctive absorption peaks of Er 3þ ions. The Judd-Ofelt (J-O) intensity parameters, oscillator strengths, spontaneous transition probabilities, branching ratios, and radiative lifetimes were successfully calculated based on the experimental absorption spectrum and the J-O theory. It was found that the presence of silver NPs nucleated and grown during the heat annealing process improves both of the photoluminescence (PL) intensity and the PL lifetime relative to the 4 I 13/2 ! 4 I 15/2 transition. Optimum PL enhancement was obtained after 10 h of heat-treatment. Such enhancements are mainly attributed to the strong local electric field induced by SPR of silver NPs and also to energy transfer from the surface of silver NPs to Er 3þ ions, whereas the quenching is ascribed to the energy transfer from Er 3þ ions to silver NPs. Using the Mc Cumber method, absorption cross-section, calculated emission cross-section, and gain cross-section for the 4 I 13/2 ! 4 I 15/2 transition were determined and compared for the doped and co-doped glasses. The present results indicate that the glass heat-treated for 10 h has good prospect as a gain medium applied for 1.53 lm band broad and high-gain erbium-doped fiber amplifiers.
