Description Visible light excitable and color tunable similar to 5% Eu3+-doped LaF3 nanocrystals (NCs), containing 9-oxido-phenalenone ligands bound to the surface as visible light sensitizers for Eu3+ dopants, have been synthesized by a facile solution-based method. The crystalline phase structure, size, composition, morphology and luminescence properties of the NCs are characterized using X-ray diffraction, high-resolution transmission electron microscopy, energy dispersive X-ray spectroscopy, and steady-state and time-resolved emission spectroscopy. The results show that these NCs are very small in size ( Eu3+ energy migration from surface-sensitized Eu3+ sites of the NCs.
