Preparation and photoluminescence of ZnGa2O4:Co
Ceramic samples of ZnGa2O4 doped with Co have been prepared. Their photolumines- cence 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 halfwidth ~ 0.5 eV, induced by the recombination of donor-acceptor...
