Abstract

Single-phase Y2BaAl4SiO12:Tb³⁺,Eu³⁺ phosphors with adjustable luminescence were successfully prepared by high-temperature solid-state reaction method. The structural, luminescent properties and energy transfer (ET) process of Y2BaAl4SiO12:Tb³⁺,Eu³⁺ phosphors were systematically analyzed with the help of X-ray diffraction (XRD), scanning electron microscopy (SEM), excitation spectra, emission spectra and photoluminescence decay curves. Tunable luminescence ranging from green through yellow and definitively to red can be achieved by elevating amounts of Eu³⁺ ions in Tb³⁺,Eu³⁺ co-doped samples. Besides, the ET mechanism and efficiency were also analyzed and the maximum ET efficiency was 67%. All the results show that Y2BaAl4SiO12:Tb³⁺,Eu³⁺ phosphors can be used in solid-state lighting.
