Abstract
BaF2 transparent ceramics with high Ce3+ dopant concentration were prepared by a high vacuum hot pressing technique. The highest Ce3+ doping concentration obtained was 50 at.%. For the first time, the BaCeF5 transparent ceramic was reported. As seen under Scanning Electronic Microscopy, all ceramic samples had an average grain size of <50 μm and were highly dense. The transmittances of 1, 10, and 50 at.% Ce3+ doped BaF2 transparent ceramics were 77.8, 73.2, and 79.5% at a wavelength of 550 nm. At the Ce3+ emission peak of 354 nm, the transmittances were 51.0, 66.1, and 31.5% for the same samples. The density increases linearly with increasing Ce3+ doping concentration and was measured to be 4.86, 5.02, and 5.62 g/cm3 for 1, 10, and 50 at.% Ce3+ doped ceramics.
