The ideal fluorescent material is excited the single lattice which can exhibit different colors of light. For example, Eu2 + / Mn2 +, Ce3 + / Mn2 + of Ce3 + / Eu2 + codoped in the same matrix can exhibit f-d or d-d electronic configuration, following the excitation radiation with different colors emission. Meanwhile, due to the role of a multi-dipole between the active ionic species, the energy transfer will occur between the band and each other. Therefore, by co-doping different rare earth ions, the host lattice of the same kind of the phosphor capable of emitting a green - yellow - orange light, has important significance for improving the luminescent properties of the phosphor, and  further expand the scope of applications

Hope to be helpful to you
