Abstract
A family of upconverting nanoparticles (UCNPs) with a tunable UV enhancement is developed via a facile approach. The design leads to a maximum 9-fold enhancement in comparison with known optimal β-phase core/shell UCNPs in water. A highly effective and rapid in situ real-time live-cell photoactivation is recorded for the first time with such nanoparticles.
摘要
通过一种简便的方法，开发了一种具有可调紫外增强功能的上转换纳米粒子（UCNPs）家族。与已知的最佳β相核/壳 UCNPs 相比，该设计使水相中的上转换效率提高了 9 倍。首次使用这种纳米粒子记录到了高效快速的原位实时活细胞光激活。
