It may be inferred the emissions at 554 nm and 658 nm undoubtedly are a two-photon approach by the relationship involving pump power and up-conversion luminescence intensity, and also the possible up-conversion emission mechanism has been explored. Meanwhile, the luminescence lifetime of green and purple light-weight decreases Together with the increasing doping concentration of Mn⁴⁺ ions. Immediately after doping Mn⁴⁺ ions, the symmetry of the matrix lattice decreases, along with the emission depth of up-conversion might be enormously improved. The research of this operate expands the investigate scope of traditional conversion supplies, and gives reference with the exploration of up-conversion luminescent materials according to transition metals.
