“…Ho 3+ ions possess numerous intermediate energy states that are minimally affected by multi-phonon decay, providing various possibilities for lasing transitions across a broad spectral range, from ultraviolet to infrared. While extensive research on the photoluminescence features of Ho 3+ ions in conventional glass systems such as silicate and phosphate can be found in the literature [19][20][21], studies specifically focusing on Ho 3+ ions in weak glass formers such as Sb 2 O 3 that exhibit low phonon losses are relatively scarce. Furthermore, the 5 I 7 level of Ho 3+ ions, which yields bright NIR emission at $2.0 μm through de-excitation to 5 I 8 transition, represents an excited state of a larger lifetime with a large stimulated emission cross-section.…”

In this study, a glass system based on heavy metal oxides, namely Pb3O4‐Sb2O3‐SiO2, was prepared with Ho2O3, Er2O3, and Tm2O3 as dopants. The prepared glasses were characterized using XRD and IR studies. The luminescence efficiencies of the three rare earth ions viz., Ho3+, Er3+, and Tm3+ in the glass system were investigated, specifically focusing on green (Ho3+, Er3+), blue (Tm3+), and near‐infrared (NIR) emissions. The optical absorption (OA) and photoluminescence (PL) spectra of RE mixed glasses displayed strong bands in the visible and NIR regions, which were analyzed using J‐O theory. The J‐O coefficients (Ωλ) found to be in the order of Ω2 > Ω4 > Ω6 for all the three glasses. Notably, the Tm3+‐doped glasses exhibited the lowest Ω2 value, which was attributed to a larger degree of disorder in the glass network due to lower fractions of Sb5+ and Pb4+ ions that take part glass network forming. Such conclusion was arrived based on the IR studies. Furthermore, the quantitative analysis of PL spectra and decay curves indicated that SbHo and SbEr glasses are suitable for efficient green emission, while SbTm glass is a promising choice for blue laser emission.

“…Phosphate glasses have some benefits over the silicate and borate glasses because of their glass forming ability [6]. From spectroscopic absorption bands and also due to hydroxyl groups has been verified the hygroscopic nature of phosphate glasses [7] [8] [9] [10]. With alkali oxides of Na cations, the phosphate glasses have improved their thermal stability [11].…”

A set of borophosphate glasses doped with alkali and transition metal (TM) ions have been synthesized. The glasses were carried through; annealing, XRD, density, DC conductivity studies. Molar volume and density varied nonlinearly. High temperature activation energy is analysed taking into consideration of Mott's SPH model. The low temperature electrical conductivity was analysed by Mott and Greaves VRH. Several polaron hopping related parameters at high temperature region and density of states at low temperature region were computed. The high temperature DC activation energy measured by conductivity, calculated numerous pertained parameters varied nonlinearly with mole fraction of vanadium content. The Study exhibits DC electrical conduction is due to both alkali and transition metal ions and thus confirms the mixed conductivity. A crossover conduction mechanism from the ionic dominant region to polaronic predominant region has been also observed.Studies revealed the single transition effect at 0.4 mol fraction of V 2 O 5 content.

“…Both Ag nanoparticles (NPs) and Au NPs have been demonstrated to be excellent sensitizers for REIs and TMIs, significantly enhancing their luminescence. − The reasons that MNPs (Ag, Au) enhance the luminescence of REIs or TMIs are summarized as follows: the localized surface plasmon resonance (LSPR) contributed by the MNPs; − or the energy transfer (ET) from the MNPs to REIs or TMIs. , However, direct evidence on ET from MNPs to REIs or TMIs, such as the excited electron or exciton transfer, is rarely reported. Herein, we have successively fabricated hybrid Au NPs and Ni-doped gallium oxide NCs precipitated GCs to probe Au’s SPR effect and ET process.…”

Hybrid noble metal (NM)−dielectric nanocrystal (NC) system has been widely used in nanophotonics, with the behavior of surface plasmon resonance (SPR) of NM yet to be explored. Herein, we fabricated Ni 2+ -doped transparent nanoglass ceramics (GCs) containing Au/Ga 2 O 3 :Ni dielectric NCs based on unique phase separation and spontaneous formation of Au nanoparticles (NPs) in a gallosilicate glass. The excitation of Au NPs leads to the injection of hot electrons into nearby NCs, which is evidenced by transient absorption spectroscopy and enhances the corresponding photoluminescence beyond Au SPR absorption. With the SPR interaction at the interface of Au/Ga 2 O 3 :Ni hybrid NCs, the photoluminescence can be enhanced by 2.8 times. Our finding suggests the utilization of SPR-induced hot electron injection through efficient "light/energy harvesting" in NM−NC GC systems for potential photonic applications.
