It can be inferred the emissions at 554 nm and 658 nm can be a two-photon approach by the relationship concerning pump electrical power and up-conversion luminescence depth, and also the attainable up-conversion emission system is explored. Meanwhile, the luminescence lifetime of inexperienced and purple light decreases Along with the escalating doping focus of Mn⁴⁺ ions. After doping Mn⁴⁺ ions, the symmetry on the matrix lattice decreases, and the emission intensity of up-conversion is going to be tremendously improved. The analyze of this do the job expands the analysis scope of regular conversion materials, and gives reference to the exploration of up-conversion luminescent products according to transition metals.

Dy³�?doped germanosilicate glass was geared up by substantial temperature melting approach. The connection among the glass's structure, the luminescent Homes as well as ratio of Ge/Si was analyzed inside the glass matrix. The affect of Dy³�?ions focus on the luminescent Homes was analyzed as well. The outcomes reveal which the samples' light-weight emission within the noticeable band is principally during the yellow region at 574 nm and blue region at 483 nm of Dy³�?ions.
