“…Figure 3 shows the up-conversion (UC) photoluminescence spectra of Er 3+ ion as pumped with 804 nm. The photoluminescence (PL) spectra of Er 3+ ion revealed three prominent bands centred at 525, 545 and 660 nm assigning to 2 H11/2 → 4 I15/2, 4 [17], [18], [19], [20]] . Ti and TiN NPs reflect potential as new plasmonic sensitizers replacing Au and Ag NPs.…”

The present work compares the impact of embedding silver (Ag), gold (Au), titanium (Ti), and titanium nitride (TiN) nanoparticles (NPs) on the absorption, photoluminescence, and Judd Ofelt properties of erbium-doped sodium zinc tellurite glass (TNZE), known as reliable solid-state laser media. Ten absorption bands of Er3+ ions in the range of 400-1600 nm are attainable where their bands correspond to their own 4f transitions. Three prominent photoluminescence (PL) bands of Er3+ ions were observed at approximately 525 nm, 545 nm, and 630 nm, corresponding to the transitions 2H11/2®4I15/2, 4S3/2®4I15/2 and 4F9/2®4I15/2, respectively. TZNE with 0.15 mol% of TiN NP inclusion showed the highest PL enhancement factor about 35 times, followed by Ti (17 times), Ag (10 times), and Au NPs (5 times), accordingly. This enhanced PL can be attributed to the strong local field induced by the localized surface plasmon resonance (LSPR) of the plasmonic NPs lies within 490-630 nm, which assists the transitions of Er3+ ions. The Judd Ofelt parameter was calculated and the TNZE glass with 0.15 mol% of TiN NPs inclusion disclosed the highest spectroscopic quality with a value of 3.57, compared to the TNZE glass with Ti (1.19), Au (0.59), and Ag NPs (0.90) inclusions. This research revealed several potential glass compositions with plasmonic nanoparticles that are attractive for the development of solid-state laser materials.

“…versus hν, as shown in Figure 3. The optical energy gap E opt was 4.41 eV higher than phosphate glasses doped with rare earth [11][12][13][14][15][16][17]. This wide optical energy gap range shows that this glass is superior and a good medium as an acceptor of the rare earth donor from the optical fiber (non-linear/laser waveguide).…”

“…To determine the spectroscopic parameters of this glass system, the Judd-Ofelt (JO) analysis was applied to the absorption intensities of Nd 3+ doped in PZLBNdYb. The detailed applications of the JO model can be found in the literature [17,18]. A brief outline of the JO analysis is given hereafter.…”

A new glass with a composition of 40P2O5-30ZnO-20LiCl-10BaF2 (in mol%), doped with 3.5Nd2O3-3.5Yb2O3, was fabricated by the quenching melt technique. The luminescence (PL) and gamma spectroscopy of the glass were investigated systematically. The spectroscopic parameters of the prepared glass, such as the optical energy gap, Judd–Ofelt parameters Ωk (where k = 2, 4 and 6), lifetimes and branching ratio of the Nd3+/Yb3+ level, were evaluated. Moreover, the shielding parameters, such as the linear and mass attenuation coefficients, mean free path and half-value layer, were evaluated. The prepared glass had a spectroscopic quality factor (Ω4/Ω6) of 0.84, which is about three-times larger than that of the most standard laser host, Nd3+:YAG. The energy of the 2P1/2 (Nd3+) level (~23,250 cm−1) was twice the energy of the Yb3+ transition (~10,290 cm−1). The value of the emission cross section (σem(λ)) of Nd3+:4F3/2→4I9/2 and Yb3+:2F5/2→2F7/2 were 2.23 × 10−24 cm2 and 2.88 × 10−24 cm2, respectively. The fabricated glass had a high emission cross section and low mean free path parameters, which makes the fabricated glass a potential candidate for multifunctional applications, such as laser emissions for medical purposes.

“…Because of the π-π* electronic transition of sp 2 hybridised C = C bonds, the intensity of the optical absorption spectra was also altered by the presence of rGO [38]. The higher peaks at 589 nm, 750 nm, and 799 nm at 0.05 Nd 3+ NPs concentrations were referred to by a hypersensitive transition (HST) following the selection rule |ΔL| ≤ 2 and |ΔJ| ≤ 2 (HST), which was "sensitive to the environment, local structure, and symmetry of the glass network" according to [39]- [40].…”

Nanomaterials based on graphene have outstanding properties, particularly in terms of optical performance. Using melt-quenching and low-cost spray coating procedures, we effectively generated a series of reduced graphene oxide-coated tellurite glasses doped with neodymium nanoparticles, denoted as rGO-ZBTNd (NPs) glasses. An X-ray diffraction study of glass samples validated the glass system's amorphous structure. FESEM morphological analysis was used to evaluate the appearance of rGO on the glass substrate and revealed the dispersion of rGO. UV-Vis spectroscopy was used to determine different absorption bands. The refractive index value calculated using the Dimitrov and Sakka equation was found to be more than n > 2.000 and in the range of 2.339 to 2.657 when compared to uncoated samples. On the basis of these findings, a new method involving rGO deposited on tellurite glass has been developed to improve the tellurite glass currently utilised in laser applications.
