La4-4xEu4xTi3O12 (x = 0.01-0.15) nanoparticles were synthesized via the polymerizable complex method. The X-ray powder diffraction (XRD) measurements and Rietveld refinements verified that all the samples crystallized in a pure trigonal perovskite structure. La4Ti3O12 has band energy of 3.88 eV, which can be greatly narrowed by Eu3+-doping. This benefits the red-shift of the optical absorption from UV- to near-UV wavelength region. La4Ti3O12 has the self-activated luminescence at room temperature with a broadband centered at 520 nm. La4-4xEu4xTi3O12 (x = 0.01-0.15) phosphors present red-emitting luminescence with the strongest (D0F2)-D-5-F-7 transition at 613 nm. The energy transfer was discussed on the doping concentration. Importantly, the phosphors present dominant absorption in near-UV region (395 nm). An experimental red-emitting lamp was fabricated using a 395 nm LED-chip in combination with the single phosphor of La4-4xEu4xTi3O12 (x = 0.1). The results indicate that La4-4xEu4xTi3O12 could be a promising candidate used in solid-state lighting and display under near UV-light.
