离子掺杂浓度比例(0~10%)逐步获得单带上转换红光发射。在此基础上,通过上转换纳米粒子表面连接近红外IR-806染料分子,808 nm激发下其上转换发光强度提高了约22倍,特别地,红绿荧光强度比从4.8增至8.4。结果表明,染料敏化可用于增强上转换单带红光发射,并提高红光色纯度,这有利于高清晰的生物成像应用。

: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 Ce

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.
