Current Projects

Advanced inorganic nanocomposites for distributed sensors of harmful radiation

Czech Science Foundation (9,056 thou. CZK)
No: GA23-05507S
Realization period: 2023-2025
Participant researcher: Pavla Nekvindová

The project targets on experimental research of preparation and properties of transparent inorganic nanocomposites containing radioluminescent ceramic nanoparticles. We will study the formation, chemical and temperature stability of radioluminescent nanoparticles Ce: YAG and Zn2SiO4 distributed in ternary inorganic glasses with the composition Y2O3-Al2O3-SiO2 and ZnO-Al2O3-SiO2. Nanocomposites will be prepared by conventional melting followed by controlled thermal recrystallization, vacuum sintering of nanoparticles or aerodynamic levitation method. Selected samples will be drawn into optical fibers. We will evaluate the effect of the structure and composition of nanocomposites on radioluminescent properties. The results will expand general knowledge about the formation of radioluminescent ceramic nanoparticles in inorganic nanocomposites and contribute to the clarification of the effect of the structure and composition of the nanocomposites on radioluminescent properties. Nanocomposites can be applied to design scintillation detectors or distributed sensors of harmful radiation.

Gradient refractive index collimators for coupling to optical fibres
