Abstract

A novel processing was developed to fabricate transparent europium (Eu³⁺) ion doped lutetia (Lu₂O₃) scintillation ceramics. The microstructural evolution of Eu³⁺:Lu₂O₃ phosphor powder under different calcining temperatures was investigated by FTIR and TEM. Highly transparent polycrystalline Lu₂O₃ ceramics were densified from as-prepared powder by pressureless sintering under 1850 °C for 6 h in flowing H₂ atmosphere. Optical linear transmittances in the visible wavelength region for Lu₂O₃ ceramic could reach as high as above 80%. Integration of the X-ray excited emission spectra showed that Lu₂O₃:5at%Eu³⁺ ceramic scintillator provided about 10 times overall emission intensity with respect to BGO single crystal at room temperature.
