It could be inferred that the emissions at 554 nm and 658 nm absolutely are a two-photon approach by the connection amongst pump energy and up-conversion luminescence depth, as well as doable up-conversion emission mechanism has become explored. In the meantime, the luminescence lifetime of green and purple light decreases While using the expanding doping concentration of Mn⁴⁺ ions. Just after doping Mn⁴⁺ ions, the symmetry from the matrix lattice decreases, and also the emission depth of up-conversion will be considerably enhanced. The examine of the perform expands the study scope of conventional conversion supplies, and delivers reference for your exploration of up-conversion luminescent resources depending on transition metals.
