Luminescence properties of Eu3+-doped Y2O3 Powder prepared by combustion synthesis were studied. Nonlinear luminescence due to Eu3+:(5)Do-F-7(2) transition was observed for excitation at 355 nm. The dynamics of luminescence signal changes with the pump laser intensity showing that different regimes are present being faster at higher intensities. (c) 2006 Elsevier B.V. All rights reserved.
