The created compound is intended to be used as a scintillator, a substance that converts x-rays into visible light. Such materials are used in medical tomographies and baggage control systems. Unlike traditional inorganic scintillators, which are often fragile, the new development combines durability and high efficiency.
The material is based on an octahedral molybdenum metal cluster surrounded by iodide and cyanide ligands. The scientists attached the clusters to a polymer compound containing silver cations and organic ligands to increase its stability and brightness. As a result, the glow intensity increased approximately a hundred times compared to the original substance.
Tests showed that the new material is resistant to heat, chemically aggressive environments and long-term irradiation. Its efficiency turned out to be comparable to commercial scintillators. Thin X-ray screens based on matter have already been made, making it possible to obtain detailed images of objects.
Development was carried out with the support of the Russian Science Foundation. Scientists from AV Nikolaev Institute of Inorganic Chemistry SB RAS, PN Lebedev Institute of Physics RAS, VV Voevodsky Institute of Chemical Kinetics and Combustion SB RAS and MV Lomonosov Moscow State University participated in the research.
