It can be inferred the emissions at 554 nm and 658 nm absolutely are a two-photon process by the connection amongst pump energy and up-conversion luminescence intensity, and also the possible up-conversion emission system is explored. In the meantime, the luminescence life of eco-friendly and red light decreases Along with the rising doping concentration of Mn⁴⁺ ions. Soon after doping Mn⁴⁺ ions, the symmetry with the matrix lattice decreases, along with the emission depth of up-conversion will be enormously improved. The review of this function expands the investigation scope of regular conversion elements, and presents reference for that exploration of up-conversion luminescent materials based upon transition metals.

.. [Demonstrate entire abstract] emission from one doped and co-doped nanoparticles have already been researched also. It had been observed that the depth and the color purity on the fluorescence emission had been enhanced significantly by co-doping A further type of ion on the doped nanoparticles and also by changing the matrix on the nanoaprticles. The experimental observations had been mentioned according to the Vitality degree composition of doped ions and the symmetry qualities of nanocrystals.
