“…Marimuthu and his co-worker also reported the luminescence quenching when the Ag concentration was large (>0.5 wt%) due to the reversed energy transfer process from Eu 3+ ions to Ag NPs [ 54 ]. A similar result was obtained by Zhao et al [ 56 , 120 ]. Gonzalez synthesized Au NPs with different sizes and discussed their influence on the luminescence of UCNPs.…”

“…The influence of distance between lanthanidedoped films and NPs films on luminescence enhancement was further performed by introducing space layer [55]. Kushlyk and his co-workers researched the Ce 3+ and Yb 3+ codoped system with different NPs concentrations and sizes and proposed that plasmonic enhancement and quenching effect is a competition [56]. Another approach to enhance the local field is using the core shell nanostructures.…”

Modulated Luminescence of Lanthanide Materials by Local Surface Plasmon Resonance Effect

Lanthanide materials have great applications in optical communication, biological fluorescence imaging, laser, and so on, due to their narrow emission bandwidths, large Stokes’ shifts, long emission lifetimes, and excellent photo-stability. However, the photon absorption cross-section of lanthanide ions is generally small, and the luminescence efficiency is relatively low. The effective improvement of the lanthanide-doped materials has been a challenge in the implementation of many applications. The local surface plasmon resonance (LSPR) effect of plasmonic nanoparticles (NPs) can improve the luminescence in different aspects: excitation enhancement induced by enhanced local field, emission enhancement induced by increased radiative decay, and quenching induced by increased non-radiative decay. In addition, plasmonic NPs can also regulate the energy transfer between two close lanthanide ions. In this review, the properties of the nanocomposite systems of lanthanide material and plasmonic NPs are presented, respectively. The mechanism of lanthanide materials regulated by plasmonic NPs and the scientific and technological discoveries of the luminescence technology are elaborated. Due to the large gap between the reported enhancement and the theoretical enhancement, some new strategies applied in lanthanide materials and related development in the plasmonic enhancing luminescence are presented.

In this paper technological aspects of preparation of silver nanostructures on garnet substrates and their impact on absorption and photoluminescence have been studied. For this purpose, the changes of plasmonic properties as a function of the Ag NPs preparation features, such as type of substrate material, sputtered silver mass thickness, temperature, and time of thermal treatments were shown. The plasmonic structures were prepared on single-crystalline YAG and GGG garnets as well as amorphous glass substrates by the magnetron sputtering technique. Nucleation and growth of Ag nanoparticles were controlled by a thermal annealing process. Two broad absorption bands peaked at 350-370 nm and 440-650 nm were observed due to quadrupole and dipole modes, respectively, of surface plasmon resonance (SPR) of Ag nanoparticles. Changes of the positions, intensities, and widths of these absorption bands related to the nanoparticle sizes, densities, and shapes are presented. Degradation of the plasmonic structures at ambient conditions, which is revealed as diminishing of the plasmonic absorption bands and associated with sulphidation of Ag nanoparticles in the natural environment, was studied in details. Theoretical simulations of the sulphidation process modelled as coating of Ag nanoparticles with silver sulphide (Ag 2 S) film confirm the experimentally observed diminishing of SPR.

“…Recently, a study concluded that, unlike large AgNPs that may enhance cerium luminescence by several times, smaller Ag nanoparticles (<50 nm) may quench the Ce 3+ signal, suggesting atypical energy transfer from Ce 3+ to Ag + . 10 Indeed, the size, shape, and concentration of the silver nanoparticles were reported to dictate the direction of energy transfer and Ag−Ce interactions in the material.…”

Role of Ag⁺ Ions in Determining Ce³⁺ Optical Properties in Fluorophosphate and Sulfophosphate Glasses

et al. 2021

Understanding the interactions among dopant species and the role of the host lattice is of fundamental importance for the chemical formulation of optically active glasses. Here, we consider the archetypal dopant pair of Ag–Ce in complex fluorophosphate (PF) and sulfophosphate (PS) matrices, in which variable bonding environments and ligand selectivity exert distinct effects on dopant properties. The addition of Ag+ to PF glasses blue-shifts the ultraviolet (UV) cutoff wavelength of Ce3+ and enhances its photoluminescence (PL) intensity. In PS matrices, the exact opposite effect is observed: red-shifting the UV cutoff and lowering the PL intensity. No Ag–Ag pairs or cluster species were found in either matrix material; however, in PS, such clustering could be triggered by secondary broad-band UV–visible irradiation. The optical properties of Ag–Ce-codoped glasses are a result of the ionocovalent character of the Ag+–O–Ce3+ bond, the cross-relaxation process between Ag+ and Ce3+, and the redox ratio of Ce3+/Ce4+. In the PF glasses, the enhancement of the Ce3+ PL intensity is due to energy transfer from Ag+ to Ce3+ and a redox shift from Ce4+ to Ce3+. The more covalent Ag+–O–Ce3+ interactions in the PS series decrease the Ce3+/Ce4+ ratio. Moreover, photoinduced Ag clustering is facilitated in the more covalent environment, which indicates that glasses commonly used for Ag nanoparticle formation, such as silicate glasses, also possess more covalent Ag+–O bonding.
