Abstract
One of the 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.
摘要
上转换纳米粒子（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设计，可将UCNP编程为具有高度可调谐的染料特征激发带。利用这些独特特性，我们开发了一种新的激发波长选择性安全成像技术。这项工作为上转换纳米粒子的激发波长带来了更大的自由度，我们相信这是该领域的一个变革者，这种方法将使许多目前受现有UCNP限制的应用成为可能。
