Multifunctional magnetic/upconversion luminescent mesoparticles, consisting of a Fe(3)O(4) nanoparticle core and a LaF(3):Yb(3+), Er(3+) nanocrystal shell, have been developed using a facile co-precipitation approach. Owing to their excellent superparamagnetic properties, superior T(2)-enhanced magnetic resonance effect and strong upconversion emissions, the as-formed mesoparticles have great potential in diverse medical diagnostics and biological imaging.
多功能磁性/上转换发光介孔粒子，由 Fe(3)O(4)纳米粒子核和 LaF(3):Yb(3+)、Er(3+)纳米晶壳组成，采用简便的共沉淀法制备。由于其优异的超顺磁性、优越的 T(2)增强磁共振效应和强上转换发射，所形成的介孔粒子在各种医学诊断和生物成像中有很大的应用潜力。
