Abstract
This report investigates the structure and optical properties of Tb3+ co-doped Au glasses, with a focus on their applicability in green luminescent optical behavior. The study of Tb3+ co-doping in the presence of Au nanoparticles (AuNPs) within glass matrices. The starting materials include SiO2, Al2O3, B2O3, CaO, Sb2O3, Na2O, K2O, SnO2, SeO2, Tb2O3, and AuNPs. Glass fabrication employs the conventional melt quenching technique, followed by comprehensive characterization of physical, optical, luminescence, and structural properties. The density values reported for the glass, ranged from 2.8269 to 2.8359 g/cm3, molar volume was 26.3382 to 26.2591 cm3/mol, and refractive index was 1.5438–1.5526. The absorption spectra consist of three absorption bands that are located at 524, 1894, and 2178 nm and are assigned to 7F6 → 5D4, 7F6 → 7F0,1,2, and 7F6 → 7F3, respectively. Photoluminescence (PL) and radioluminescence (RL) show similar trend and the optical properties are scrutinized using a spectrofluorometer. Size of the nanoparticle was evaluated and show around 8–16 nm and interplanar distance showing 2.1 Å. This study underscores the potential of Tb3+ and Au co-doped materials as promising for green optical applications.
