Abstract
In this contemporary technological world, Eu3+ ions doped metal nanoparticles embedded amorphous materials are receiving overwhelming interest due to their potentiality in developing LEDs and solid-state lasers for photonic devices applications. Due to which, in the present investigation, we made an attempt to enhance the spectroscopic performance of Eu3+ ions in the proposed glasses. A new set of Eu3+ ions doped Ag NPs precipitated sodium borate glasses were fabricated using a simple conservative melt quenching method. The results of XRD support the glasses' amorphous phase by exhibiting a large diffuse ring at 20–40°. The optical absorption spectra results reveal that the observed absorption peaks originated from 7F0 and 7F1 ground states to various excited states of Eu3+ ions and as usual the observed SPR peak induced by Ag NPs underwent regular red-shift. The presence of spherical and well-dispersed Ag NPs in the glass matrix was confirmed by HR-TEM images. PL emission spectra of the studied glass samples showed that the highest peak emission intensity for NLE-1 glass, and also observed that the enhanced peak intensities for all NLE glasses with precipitation of Ag NPs. This PL intensity improvement is due to the transfer of energy from small clusters of Ag NPs to Eu3+ ions. The yield of the 5D0→7FJ emissions is demonstrated utilizing the 1931 CIE chromaticity diagram. In addition, the emission of Eu3+ ions has been analyzed using the Judd-Ofelt emission theory.
