Abstract

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.
