Description
Summary:The synthesis of lutetium silicate nanoparticles doped with Ce3+ using the new salt-supported high temperature (SSHT) method is reported. This mechanochemical–thermal method enables the synthesis of nanoparticles without aggregation even after long calcination times of 48 h at high temperatures. These nanoparticles are characterized by powder X-ray diffraction (PXRD), transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), and Fourier transform infrared spectroscopy (FT-IR). Their optical properties, including UV luminescence and X-ray scintillation, are reported. These nanoparticles show strong luminescent and scintillation behavior. This SSHT method is general and can be used for the synthesis of other ternary and quaternary nanoparticle systems.
