摘要

Using urea as fuel, a solution combustion synthesis process was employed to prepare pristine and Tb3+-doped Bi2Al4O9 phosphor. Using powder XRD, the produced material’s orthorhombic mullite-type structure with Pbam (55) space group was confirmed. SEM and EDS were used to evaluate the sample’s morphology and chemical composition. The Hitachi F-7100 fluorescence spectrophotometer was used to record lifespan and photoluminescence measurements. The PL spectra of Bi2Al4O9:Tb3+ exhibited a significant cyan-blue emission with the highest emission occurring around 545 nm for excitation wavelength 285 nm attributed to 5D4 → 7Fj (j = 0 to 6) transitions. Synthesized phosphor has potential applications in field emission display systems and solid-state lighting (Mater. Today. Proc. 18: 1132-1137 (2019)).
