Description

Ceramic samples of ZnGa2O4 doped with Co have been prepared. Their photoluminescence spectra measured at laser excitation (λ=351 nm) and various temperatures (10 - 300 K) contain a wide band, centered at 2.8 eV (10 K) with its half width ∼ 0.5 eV, induced by the recombination of donor-acceptor pairs. The subsequent thermal annealing leads to its concentration quenching. (authors)
