摘要	Single-band red upconversion emission has important applications for high-resolution biomarkers and 3-dimensional color display. However, the cross-relaxation of Ho3+/Ce3+ co-doping system normally yield the weak single-band red emission. In this paper, the dye-sensitized NaYF4:Yb/Ho/Ce(20%/2%/10%)@NaYF4:Nd(20%) nanoparticles were prepared to address such an issue. Highly uniform upconversion nanoparticles were prepared by solvothermal method, and the single-band red emission was obtained by increasing the Ce3+ doping concentration (from 0% to 10%) inside the core. When the near-infrared dyes of IR-806 were further conjugated, the upconversion luminescence intensity exhibited a 22-fold enhancement, and the red-to-green emission ratio also increased from 4.8 to 8.4. This paper provides a new way to improve the intensity and the purity of single-band red upconversion luminescence through dye sensitization, which is beneficial to high-resolution bioimaging. 2020, Science Press.
