“…Haouari et al explored the synthesis and characterization of tellurite glasses containing AgNPs doped with Eu 3+ ions. 34 The obtained samples were heat treated at the same temperature but for different periods. The most interesting result of this work is that there is an enhancement in the luminescence of Eu 3+ due to the surface plasmon resonance of the AgNPs inside the glass matrix.…”

“…The Ω 6 parameter was not determined in this study due to the unregistered emission band, located in the NIR range of wavelength, that corresponds to the 5 D 0 → 7 F 6 transition band. The Ω 2 parameter is known to be structure sensitive and also depends on the covalence of Eu 3+ bonds with the ligand [43][44][45][46]. It is determined from 5 D 0 → 7 F 2 hypersensitive transition.…”

Glass-ceramics with the composition B2O3-Bi2O3-SrF2 were synthesized by the conventional melt-quenching technique and subsequent crystallization of the parental glasses. The temperature at which the ceramization was carried out was selected based on differential scanning calorimetry (DSC) analysis. The structure of the studied materials and the formation of SrF2 nanocrystals were confirmed by the Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) techniques. It was found that the amount of strontium fluoride introduced into the parental borate-bismuth glass has a significant impact on the growth of SrF2 nanocrystals. In particular, the influence of the crystalline SrF2 phase on luminescence intensity and kinetics was studied using Eu2O3-doped samples. An increase in luminescence intensity was observed in the samples in which SrF2 nanocrystals were formed. This is most likely related to the fact that some of the Eu3+ ions were (after annealing of the glass) located in the crystalline structure of strontium fluoride. This was confirmed both by the luminescence lifetime obtained based on the luminescence decay curves and the calculated Judd–Ofelt parameters, Ω2 and Ω4. The results achieved confirm that the glasses and glass-ceramics described in this work could be considered as a new phosphor for light-emitting diodes (LEDs).

“…14 There are numerous studies dedicated to examining the interaction between plasmonic NPs and luminescent materials. [15][16][17][18][19][20][21] Research conducted in this area has provided evidence demonstrating that plasmonic NPs, when present within a luminescent material, can enhance its luminescence intensity. The combination of silver NPs and the YAG:Ce phosphor is considered to be a promising option due to the almost identical location of the maximum silver NPs plasmon resonance (≈450 nm) and the excitation wavelength of YAG:Ce.…”

In this study, silver nanoparticles (NPs) were considered for the first time as a sintering additive in the manufacture of YAG:Ce luminescent ceramics. The influence of the addition of silver NPs on the sintering kinetics of ceramics was investigated. It was found that the addition of Ag NPs in the concentration range of 0.027–0.44 wt% does not result in the formation of secondary phases in YAG:Ce ceramics. It was demonstrated that the light transmission of ceramics is dependent on the concentration of Ag NPs. The use of NPs additive has made it possible to increase the light transmission of ceramics compared with the reference sample without sintering additives. The combination of two sintering additives, TEOS and silver NPs, enables the achievement of enhanced optical transparency in ceramics compared to the individual application of sintering additives. At an optimal silver concentration of 0.11 wt%, in combination with 0.5 wt% TEOS, a ceramic light transmission value of 77% was attained. The study has identified a correlation between the luminescence intensity of YAG:Ce ceramics and the concentration of silver NPs. It was observed that the utilization of low concentrations of the Ag additive had negligible impact on the luminescence properties, whereas the introduction of high concentrations of Ag NPs led to a deterioration in the luminescence and optical transparency of the ceramic.
