- Аннотация: Intense white-light color emission of lanthanide-doped core-shell structured particles at microscale level was presented under 980 nm excitation. The prepared NaYF4:Yb/Er@ NaYF4:Yb/Tm microcrystals not only can effectively prevent the deleterious cross-relaxation that occurs between the Er3þ and Tm3þ due to the location of the activator ions within different layers, but also possess a high luminescence effi- ciency due to dimensions of the micro-scale structure. The core-shell structured microcrystals presented satisfactory capacity for color control in the white region. The results show great potential in attaining white light-emitting diodes within the field emission display on specific device applications. Further- more, the core-shell microcrystals emit white-light that presents obvious and distinct lifetimes of green, red, and blue emissions, which could achieve multicolor emissions by setting a suitable delay time. This feature demonstrates that the core-shell structured microrods offer practical use as security ink to prevent forgery, such as in identifying currency.
