Problems solved by technology

If one-dimensional long-lasting luminescent materials are arranged in an orderly manner, long-lasting luminescent nano-arrays can be formed. Using porous alumina (AAO) templates is a very effective method. AAO templates are widely used in the preparation of carbon nanotubes, metals, And one-dimensional nanomaterials such as single metal oxides and their arrays (such as patents CN101033080, CN101629320), but for materials containing multiple metal ion oxides, it is very difficult to prepare nano-arrays using AAO templates. Red long-lasting nano-arrays have not been reported
