✦ Synopsis

LaF 3 nanoparticles were grown in aqueous solutions containing different surfactants to realize stronger absorption cross-sections and energy transfer to the optical center. Benzoic acid and phthalic acid were selected as the surfactants attached to the nanoparticles. RE-doped LaF 3 samples prepared with these surfactants showed enhanced emissions due to energy transfer from the organic ligand.

Block copolymers spontaneously self-organize into nanometer-scale structures and are therefore of great interest for emerging nanomaterials and nanotechnologies. [1] Welldefined polymer aggregates, such as spheres, vesicles, rods, tubules, and lamellae, form in selective solvents. [1][2][3][4][5][6]
