Surfactant effect on and luminescence tuning of lanthanide-doped ScPO4 center dot 2H(2)O microparticles

摘要

Herein we report the effect of surfactant molecules, i.e., trisodium citrate, on the morphology, size evolution, as well as the growth mechanism of ScPO4 center dot 2H(2)O:Ln (Ln = Ce/Tb/Eu, Yb/Er) microparticles, which are synthesized via a one-pot hydrothermal method. The up-and down-conversion photoluminescence and dynamics of ScPO4 center dot 2H(2)O:Ln microparticles, including the decay time, quantum efficiency, and the energy transfer mechanism with different dopants, are further investigated. Finally, a potential application of these materials as luminescent display inks is demonstrated.
