Abstract: Visible photoluminescence and absorption spectra of the metamict and annealing-recrystallized fergusonite and brocenite, found in Bayun Obo ore deposit in China, were determined and discussed. The results show that the glow centers of the fergusonite group minerals are Er3+ and Eu3+ when 488.0 and 514.5 nm lasers are used as excitation sources. The luminescence of fergusonites results mainly from Er3+, whereas that of brocenites is produced by Er3+ and Eu3+. The absorption spectra indicate that Nd3+ may be an important sensitizer to the luminescence of Er3+ and Eu3+.
