Abstract
Terbium ion doped MO–Al2O3 (M = Mg, Ca, Sr and Ba) series phosphors have been synthesized through combustion technique and their luminescence properties have been studied and compared. Terbium ion in different phosphors has shown different fluorescence properties due to the presence of different ratios of Tb3+ and Tb4+ states in different samples. The UV/Visible absorption and XPS techniques have been used to probe the existence of Tb3+ and Tb4+ states. The host sensitive 4f–5d and the charge transfer transitions enabled the use of terbium ion as an indicator of the structure.
