Abstract: LB films of 4-hexadecyloxybenzoic-terbium by using the subphase containing Tb3+ were prepared. The monolayer behavior of 4-hexadecyloxybenzoic acid (HOBA) on the subphase containing rare earth ions was studied. IR and UV spectra show that the rare earth ions were bound to carboxylic acid head groups and the coordination took place between the polar head group and the rare earth ions. The luminescence spectra show that the LB films have the fine luminescence properties, and the LB films emit strong luminescence under UV light irradiation.
