It could be inferred that the emissions at 554 nm and 658 nm certainly are a two-photon method by the relationship among pump energy and up-conversion luminescence depth, plus the achievable up-conversion emission system has long been explored. Meanwhile, the luminescence life of inexperienced and crimson mild decreases Using the expanding doping concentration of Mn⁴⁺ ions. Immediately after doping Mn⁴⁺ ions, the symmetry from the matrix lattice decreases, plus the emission depth of up-conversion will probably be enormously enhanced. The study of this operate expands the analysis scope of common conversion supplies, and presents reference with the exploration of up-conversion luminescent components dependant on changeover metals.
