It might be inferred which the emissions at 554 nm and 658 nm undoubtedly are a two-photon process by the connection involving pump ability and up-conversion luminescence depth, plus the feasible up-conversion emission system has been explored. In the meantime, the luminescence lifetime of inexperienced and red mild decreases With all the raising doping focus of Mn⁴⁺ ions. After doping Mn⁴⁺ ions, the symmetry with the matrix lattice decreases, as well as emission depth of up-conversion will likely be drastically enhanced. The review of the operate expands the study scope of conventional conversion supplies, and delivers reference to the exploration of up-conversion luminescent supplies based upon changeover metals.
