Power Generation Characteristics of Cr-doped Al2O3 Transparent Ceramics for Nuclear Battery Application
3Cr 0.05-1.0%-dopedAl 2 O 3 ceramics were synthesized by spark plasma and vacuum sintering to compare their power generation properties under -, -and X-ray irradiations for nuclear battery application.Moreover, Cr 0.6%-doped Al 2 O 3 ceramics with different thicknesses fabricated by vacuum sintering were prepared to investigate the effects of sample size on power generation properties.The same as other phosphors, they showed the optimum Cr concentration in this specific application.The power generation decreased with increasing sample thickness under -and -ray irradiations, whereas the optimum sample size existed under X-ray irradiation.
