The system Al₂O₃-B₂O₃ containing Ce³⁺ and Tb³⁺ ions was investigated for the first time.It was found that certain compositions give rise to a new highly efficient green luminescentmaterial. The investigation of structure by XRD, ¹¹B MAS NMR spectra, IR spectra, high-resolution electron microscopy, and selected area diffraction images reveals that a crystallinephase and an amorphous phase coexist in the sample. The electron-dispersive X-ray analysisand luminescent studies reveal that the Ce³⁺ and Tb³⁺ ions are doped into the amorphousphase.
