Work

The aim of the project is the development technological approaches to obtaining luminescent microcrystalline ZnWO4 powder by the method of solid-phase synthesis and composite material based on it. The project is aimed at continuing the research conducted within the NSD under the code "Scanner" (2017-2018), which resulted in the development of a method of obtaining microcrystalline scintillation powder ZnWO4 by solid-phase synthesis (with the addition of LiNO3) and a method of manufacturing composite materials based on it. It is planned to investigate the influence of impurities (Li2SO4, Rb2SO4, Cs2SO4 and ZnSO4) on the reacting mixture of oxides on the process of solid-phase synthesis (as mineralizers) and on the luminescent characteristics of the synthesized powders. Also, it’s planned to improve the method of compaction of the synthesized powder in order to improve the spatial resolution and light output, by varying the thickness of the composite, the size of the crystalline granules of the filler and its concentration that will apply the proposed composite materials in non-destructive testing systems and industrial welds. And further improvement of the inertial characteristics of the studied composite scintillators will allow their use in medical computed tomography.
