Scintillation properties of zinc-silicate glass-ceramics based on Zn2SiO4 willemite phase

Original language description

The glass-ceramics samples were prepared via controlled heat treatment of precursor glass synthesized using the standard melt-quenching method. The glass composition (in mol.%) was 14.3Na2O–35.7ZnO–49.4SiO2–0.6 Al2O3 and the annealing temperatures were varied at 750, 800, 850 and 900 ◦C. X-ray diffraction measurements identified the presence of several crystalline phases, including Na2ZnSiO4, triclinic Zn2SiO4, and rhombohedral Zn2SiO4 (willemite), with their formation dependent on the annealing temperature. Transmission electron microscopy confirmed the presence of crystalline phase nanoparticles with a size of 10–30 nm, where increased annealing temperatures resulted in a higher number of nanoparticles and reduced particle sizes. The optical, scintillation and luminescence properties of prepared glass and glass-ceramics were investigated by spectroscopic ellipsometry and using the time-resolved luminescence spectroscopy, revealing a decrease in refractive index and chromatic dispersion with higher annealing temperatures. The intense UV emission peaking at around 350 nm, overcoming the standard Bi4Ge3O12 scintillator intensity by more than 500 %, for all the samples was discovered under the X-ray excitation (40 kV). The bandgap of willemite nanoparticles was measured at approximately 205–220 nm and the corresponding scintillation decay with leading component in sub-nanosecond scale was detected. These findings highlight the potential of Zn2SiO4-based glass-ceramics, particularly those containing willemite nanoparticles, as promising materials for advanced distributed radioluminescent sensors and fast scintillation applications. The impact of annealing conditions on the material’s structural and optical properties is discussed in detail.
