This project aims to tackle the major challenge of upconversion nanosystems – their brightness. It will centre on building a donor/acceptor-ordered nanosystem to improve the energy transfer efficiency in hybrid nanomaterials. This ordered system will significantly improve the brightness of hybrid nanoparticles at low irradiance. Expected outcomes include a fundamental understanding of energy transfer mechanisms at sub-nm scales and a new strategy to brighten the upconversion nanomaterials. This project should push upconversion nanoscience to a new generation and provide significant benefits in ultra-sensitive biomolecular assays and in vivo bioimaging.

这个项目旨在解决上转换纳米系统的主要挑战——它们的亮度。它将集中于建立一个供体/受体有序的纳米系统，以提高混合纳米材料的能量传递效率。该有序体系将显著提高混合纳米粒子在低辐照度下的亮度。预期的结果包括对亚纳米尺度的能量转移机制的基本理解和照亮上转换纳米材料的新策略。该项目将把纳米科学推向新一代，并在超灵敏生物分子分析和体内生物成像方面提供显著的好处。
