The international research team composed of Chinese, Japanese and Russian scientists synthesized new crystal materials with rare earth oxides and elucidated the structure and properties of the new materials. Relevant research results published in the European Journal of Chemistry. X-ray analysis showed that the The material is a new compound with a unique spectrum that can be used in the future to make electronic devices such as displays.
Researchers from China's Bohai University and Northeastern University have synthesized rare earth nitrate with sulfate and ammonium hydrate to synthesize a new compound, after which researchers from China, Japan and Russia formed an international team to work together to determine the crystal of the new compound The new compound has a unique spectrum compared with other luminescent rare earth compounds that have been found.
Maximilomuoyayev, a professor of X-ray structure analysis at the Federal Institute of Physics of the Siberian Branch of the Russian Academy of Sciences in Siberia, confirmed through research that the new compound is structurally a completely new substance.
According to Molokayev, the main difficulty in analyzing the structure of a compound is that it is necessary to obtain a single crystal of a novel compound and to analyze the single crystal structure of the powdery material by X-ray diffraction more complicated than analyzing other substances By analyzing the X - ray images, Moloyev found that the new phosphors consisted of tetrahedral sulfates and rare earth ions surrounding the oxygen atoms, leaving the tetrahedra of sulfur oxides in a disorderly arrangement.
The biggest feature of this new compound is that when heated to 800 degrees Celsius will synthesize phosphors, and the synthesis process produces only water, and the current production of similar phosphors usually produce toxic substances. Russian scientists believe that the future of this new compound In the production of displays and other electronic equipment has broad application prospects, will effectively reduce the synthesis of phosphors on the surrounding environment hazards.
