Abstract

A facile, but effective, method has been developed for large-scale preparation of NaLa(MoO₄)₂ nanorods and microflowers co-doped with Eu³⁺ and Tb³⁺ ions (abbreviated as: NLM:Ln³⁺). The as-synthesized nanomaterials possess a pure tetragonal phase with variable morphologies from shuttle-like nanorods to microflowers by controlling the reaction temperature and the amount of ethylene glycol used. Consequently, the resulting nanomaterials exhibit superb luminescent emissions over the visible region from red through yellow to green by simply changing the relative doping ratios of Eu³⁺ to Tb³⁺ ions. Biocompatibility study indicates that the addition of NLM:Ln³⁺ nanomaterials can stimulate the growth of normal human retinal pigment epithelium (ARPE-19) cells. Therefore, the newly-developed NaLa(MoO₄)₂ nanomaterials hold potentials for a wide range of multifunctional applications, including bioimaging, security protection, optical display, optoelectronics for information storage, and cell stimulation.
