“…The Δ E value was 0.34 eV on calculation in Equation . Compared with the reported Δ E s for Eu 3+ ‐activated titanates such as CaTiO 3 :Eu 3+ (150 meV), (Ca, Zn)TiO 3 :Eu 3+ ( E = 0.2876 eV) etc., it can be suggested that La 4‐4x Eu 4x Ti 3 O 12 ( x = 0.01‐0.15) possesses an excellent stability on the thermal quenching.…”

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 5D0→7F2 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.

“…(b). One can see the emission intensity increases first, and then decreases with increasing the Eu doping content, which is considered due to the concentration quenching effect . The maximum emission intensity is at 7% and 9% Eu doping content for the CTE cubes with the size of 248 nm and 815 nm, respectively.…”

In this article Ca TiO :xEu single crystalline particles with a cubic morphology and average size of 248 to 815 nm were synthesized by a solvothermal method. The structural and optical properties of the Ca TiO :xEu cubes were investigated, the formation mechanism of the cubes were analyzed and discussed, and the influence of Eu doping content and cubic size on the photoluminescence were examined. The differences in the photoluminescence between Ca TiO :xEu cubic crystals and nanoparticles was analyzed. It was found that an addition of a small amount of water can substantially reduce the size of the cubes. An obvious red emission band centered at 615 nm was observed under the excitation at 395 nm for the cubes. Our results demonstrate CaTiO cubes are good host materials for designing red phosphors.
