A new method for obtaining substances necessary for X-ray machines, as well as for glow-in-the-dark paints and accelerators of chemical processes, has been discovered at Tomsk State University of Architecture and Building (TSUAB). This method is distinguished by the simplicity of equipment operation and the ability to adapt to industrial requirements.
Luminescence is the ability of substances to emit light when exposed to external factors. This phenomenon is widely used in medicine, chemical and biological research, as well as in the creation of decorative glow-in-the-dark drawings and car tuning, TSUAB specialists note.
To create phosphors that emit light, a certain chemical structure is required. Modern phosphors contain elements such as gadolinium (Gd), europium (Eu), and terbium (Tb), which are quite rare in the earth's crust. This significantly increases the cost of components for X-ray machines and special paints, explains Andrey Mostovshchikov, Director of the Research Institute of Building Materials at TSUAB.
The TSUAB team has developed and already patented a new method for obtaining ingredients for luminescent paints, using oxygen, molybdenum (Mo), and alkaline earth metal ions. The method involves the use of equipment available in any chemical laboratory and at most industrial enterprises.
We place molybdenum powder in a special container, heat it in the presence of compounds of other components of the target substance, and at a certain point of heating, the reaction we need occurs very quickly. At the same time, the yield of the target product is at least 95%.
To ensure high luminous efficiency, the phosphor must be in the form of a powder, while most modern substances are produced in monolithic form. Using the new technology, the product is immediately obtained in powder form and does not require additional grinding processes, the scientist emphasized.
