The photophysical and nonlinear optical properties of water-soluble chromophore-functionalised tris-dipicolinate complexes LnL3 (Ln=Yb and Nd) are thoroughly studied, revealing that only the Yb(III) luminescence can be sensitized by a two-photon excitation process. The stability of the complex in water is strongly enhanced by embedding in dispersible organosilicate nanoparticles (NPs). Finally, the spectroscopic properties of [NBu4]3 [YbL3] are studied in solution and in the solid state. The high brightness of the NPs allows imaging them as single objects using a modified two-photon microscopy setup in a NIR-to-NIR configuration.
对水溶性发色团功能化的三吡啶甲酸配合物LnL3（Ln = Yb和Nd）的光物理和非线性光学性质进行了深入研究，结果表明只有Yb(III)发光可以通过双光子激发过程进行敏化。通过嵌入可分散的有机硅纳米颗粒（NPs），配合物在水中的稳定性得到了显著增强。最后，研究了[NBu4]3 [YbL3]在溶液和固态中的光谱性质。NPs的高亮度使得可以使用改进的双光子显微镜装置在近红外到近红外配置下将它们作为单个物体进行成像。
