“…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.…”

The emerging field of matermetallomics refers to all research activities aimed at the clarification of the role and function of metallic elements in materials. This paper discusses the concept of matermetallomics and the related analytical techniques used for probing the interactions between structure-activity relationships. The main object of matermetallomics research is metallic elements in materials, and includes the significance and contributions to materials science. This paper also introduces the analytical approaches used in matermetallomics, which includes the techniques of imaging, spectroscopic, X-ray-based, ion beam, MS-based and atomic spectrometry. Recently, this technology has been successfully applied to some novel materials, such as energy materials, gas separation materials, alloy materials, catalytic materials, polymer materials and others for specific applications. 2-7 Studies have shown that the composition as genes of materials is an important link in the chain of processing, structure, properties, and performance, which is worthy of attention and discussion.

“…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.…”

The article presents a method to synthesize aluminum oxynitride (AlON) doped with cobalt ions at concentrations ranging from 0.01 at.% to 5 at.%. The phase and elemental composition of the samples and their optical properties have been studied upon variation of the cobalt content. Five emission bands in the pulsed cathodoluminescence spectra are attributed to intrinsic defects and impurities in AlON. The optical gap of AlON:Co estimated using the Tauc method are in the range of 5.72–5.84 eV and are significantly influenced by the oxygen content in the AlON host.
