UCNP发展的关键障碍之一是其激发波长的选择极其有限。我们报告了一种通用的设计，将UCNP编程为具有高度可调的染料特征激发带。利用这种独特的性质，我们能够开发出一种新的激发波长选择性安全成像。这项工作释放了上转换纳米颗粒激发波长的更大自由度，我们相信它将改变该领域的游戏规则，这种方法将使目前受到现有UCNP限制的许多应用成为可能。
One of key roadblocks in UCNP development is its extremely limited choices of excitation wavelengths. We report a generic design to program UCNPs to possess highly tunable dye characteristic excitation bands. Using such distinctive properties, we were able to develop a new excitation wavelength selective security imaging. This work unleashed the greater freedom of the excitation wavelengths of the upconversion nanoparticles and we believe it is a game-changer in the field and this method will enable numerous applications that are currently limited by existing UCNPs.
