摘要：Currently, the development of phosphors for full-spectrum lighting is a prominent research area in the field of illumination. In this study, a novel and highly efficient yellow phosphor (Ba3Sc2(BO3)4: Eu2+, BSBO: Eu2+) is synthesized via the high-temperature solid-phase method for the first time. The excitation spectrum of this phosphor ranges from 225 to 480nm, with a peak at 365nm. The emission spectrum ranges from 450 to 720nm, peaking at 555nm, with a full width at half maximum (FWHM) of 113nm. BSBO: Eu2+ shows outstanding quantum efficiencies (IQE = 94.3%, EQE = 33.3%). The emission spectrum and luminescent color can be tuned through cation substitution. The thermal stability of BSBO: Eu2+ is significantly enhanced by the partial replacement of Sc ions with smaller Al and Ga ions. To illustrate its practical application potential in full-spectrum lighting, BSBO: Eu2+ is combined with commercially available blue and red phosphors, resulting in a WLED warm light source with an outstanding color rendering index (Ra) of 94.4% and a correlated color temperature (CCT) of 3865 K. These results highlight the substantial potential of BSBO: Eu2+ in full-spectrum lighting applications. ? 2025 Wiley-VCH GmbH.
