摘要

Manganese materials with attractive optical properties have been proposed for applications in such areas as photonics, light-emitting diodes, and bioimaging. In this paper, we have demonstrated multicolor Mn²⁺luminescence in the visible region by controlling Ce³⁺-Mn²⁺energy transfer in rare earth nanocrystals [NCs]. CeF3 and CePO4 NCs doped with Mn²⁺have been prepared and can be well dispersed in aqueous solutions. Under ultraviolet light excitation, both the CeF3:Mn and CePO4:Mn NCs exhibit Mn²⁺luminescence, yet their output colors are green and orange, respectively. By optimizing Mn²⁺doping concentrations, Mn²⁺luminescence quantum efficiency and Ce³⁺-Mn²⁺energy transfer efficiency can respectively reach 14% and 60% in the CeF3:Mn NCs.
