Tunable luminescence and structural modifications in Eu³⁺/Li⁺ Co-doped YBa₃(BO₃)₃ phosphors for LEDs
Eu³⁺-doped and Eu³⁺/Li⁺ co-doped YBa₃(BO₃)₃ (YBBO) phosphors were synthesized via a microwave-assisted sol-gel combustion method for warm white LED applications. Li⁺ co-doping improved crystallinity and luminescence efficiency. XRD with Rietveld refinement confirmed single-phase YBBO with lattice modifications due to doping. SEM-EDS analysis revealed improved particle densification and uniformity, while FTIR and Raman spectra confirmed alterations in the borate network. Photoluminescence studies showed a dominant red emission at 611 nm. The intensity corresponding to 0.05 mol Eu³⁺ doping was approximately 8.38-fold higher than that of the 0.005 mol Eu³⁺ sample, indicating enhanced luminescence efficiency before the onset of concentration quenching. The phosphor exhibited high color purity (88.3 %) based on CIE coordinates, making it suitable for color evaluation over CCT. Time-resolved PL measurements showed prolonged lifetimes and decreased non-radiative decay. These results demonstrate the potential of YBBO:Eu³⁺/Li⁺ as a highly efficient red-emitting phosphor for next-generation optoelectronic and solid-state lighting applications.
期刊介绍:
Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. Papers purely on thermodynamics or theoretical calculations (e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Topics covered include functional materials (e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.); electrochemistry and solid-state ionics (e.g., photovoltaics, batteries, sensors, and fuel cells); nanomaterials, graphene, and nanocomposites; luminescence and photocatalysis; crystal-structure and defect-structure analysis; novel electronics; non-crystalline solids; flexible electronics; protein-material interactions; and polymeric ion-exchange membranes.
