Sensitization effects in nitride materials doped with rare-earth metals ions

Matermetallomics: Concept And Analytical Methodology

“…14 Bimetallic doping caused shifts of the absorption and emission band maxima in the luminescence spectra and the appearance of optical properties unattainable for mono-doped materials. 29 Moreover, such systems often demonstrate the sensitization effect which allows a considerable enhancement of the luminescence intensity and thus avoids the limitations imposed by the concentration quenching effect. Experimental and theoretical studies have proven that incorporation of co-dopants advances the photocatalytic properties of graphite gallium nitride (g-C3N4) photocatalyst more efficiently.…”

Synthesis and spectroscopic properties of aluminum oxynitride doped with 3d-metal ions: the case of γ-AlON:Co

“…The optical properties of double-doped AlONs are also considered, e.g., with the ion pairs of Eu 2+ /Ce 3+ [21,22], Eu 2+ /Tb 3+ [22,23] and Ce 3+ /Tb 3+ [22,24,25]. The features of synthesis of aluminum oxynitrides, their physical and chemical properties, and solubility limits of the dopants in AlON [26][27][28][29][30][31] have been well established. Preparation of AlON-based ceramics encounters also some technological issues and the presence of secondary phases formed under an excess of the dopants is one of them.…”
