The luminescence of Bi 3Ψ in the pyrochlore Gd 2 GaSbO 7 is evaluated in the 15 to 300 K temperature range. The rapid thermal quenching of Bi 3Ψ luminescence, despite the small Stokes shift, is postulated to involve a photoionization process arising from the interaction between the Bi 3Ψ 3 P 0, 1 ex
