Abstract
Controlled synthesis of functional photoluminescent materials are of particular interest due to their fascinating optical properties. Herein, highly uniform SiO2:xTb3+spherical nanoparticles are fabricated by a facile sol-gel method. The structure, morphology, compositions, and luminescence properties of As-prepared samples were well investigated using TEM, SEM, EDX, XRD, XPS and luminescence spectroscopy. The PL intensity of SiO2:xTb3+spherical nanoparticles is Tb3+ ions concentration dependent achieved a maximum at 3 mol % of Tb3+. Particularly, SiO2:xTb3+spherical nanoparticles exhibit a green emission corresponding to 5D4→7Fj transition (541 nm) of Tb3+. These results show that As-prepared phosphors may find potential application in solid-state lighting fields.
