Summary:The invention belongs to the technical field of luminescent materials and particularly relates to erbium ion sensitized upconversion phosphor as well as a preparation method and an application thereof. According to the upconversion phosphor, NaLuF4 is taken as a substrate, Tm<3+> and Ho<3+> are taken as energy trapping centers, and Er<3+> is taken as sensitization ions and activation ions. Er<3+>is taken as the sensitization ions and the activation ions simultaneously in a high Er<3+> doping manner, and red upconversion luminescence with high impurity can be obtained. Doping concentration ofEr<3+> can be reduced by adopting Tm<3+> and Ho<3+> as the energy trapping centers simultaneously, so that the probability of concentration quenching is reduced effectively, and red upconversion luminescence with high purity, high intensity and high red-green ratio is realized more easily. The preparation process of the upconversion phosphor is simple, short in period, easy to operate, pollution-free and suitable for large
