Description
Summary:Rare-earth elements [Formula: see text]-, [Formula: see text]-, [Formula: see text]- and [Formula: see text]-doped ([Formula: see text][Formula: see text])[Formula: see text][Formula: see text][Formula: see text][Formula: see text]O3 ceramics (abbreviated as KNLNB-0.1%RE) were prepared by conventional solid-phase sintering method. The structure, transparency, energy storage and photoluminescence properties of the samples are investigated. All ceramics have the pseudo-cubic phase structure without the impurity phase at room temperature. KNLNB-0.1%RE ceramics exhibit excellent optical transmittance, with KNLNB-0.1%Ho achieving 71.8% transmittance in the visible wavelength range (780[Formula: see text]nm) and largest effective energy storage density of 1.45[Formula: see text]J/cm3. In our experiments, rare-earth-doped KNLNB ceramics exhibit photoluminescence effects. This work facilitates the development of transparent energy storage ceramics with fluorescent effects.
