Abstract

Competitive incorporation of Eu³⁺ and Na⁺ ions into citric acid-passivated hydroxyapatite (Cit/HA) particles was investigated for improving the photoluminescence internal quantum yield (η_int). As a result, Eu³⁺/Na⁺-co-doped Cit/HA (Cit/HA:Eu/Na) particles were successfully synthesized to control the Eu³⁺ states inside/outside the HA structure. The optimum Na⁺ concentration would suppress the surface deactivation of the Cit/HA:Eu/Na particles, leading to the higher η_int value.
