Lead-free ferroelectric upconversion fluorescent ceramic material as well as preparation method and application thereof
The invention discloses a lead-free ferroelectric upconversion fluorescent ceramic material which is prepared by doping a rare-earth element with an oxide matrix with a perovskite structure. The material is characterized in that a chemical formula of the material is Bi0.5-x-yNa0.5YbxPryTiO3, wherein x is not less than 0.005 and not more than 0.04 and y is not less than 0.0003 and not more than 0.0015. The invention further discloses a preparation method and an application of the material. Compared with the prior art, the material has the advantages that the upconversion fluorescent radiation property in a ferroelectric substance can be realized by adding the trivalent rare-earth element Pr<3+> into (Bi0.5Na0.5)TiO3, so that the material becomes a multifunctional material with a controllable fluorescent electric field, and electricity leakage of the (Bi0.5Na0.5)TiO3 ceramic also can be improved.
