    Ce3+ and Eu2+ co-doped BaSiO3 phosphors simultaneously emit bluish purple and yellow double-color light under the excitation of 335 nm ultraviolet (UV) light. The asymmetric blue-violet emission originates from Ce3+, whereas the yellow emission originates from Eu2+. The luminescent spectra reveal that an efficient resonance energy transfer can occur from the Ce3+ to the Eu2+ ions. Based on the principle of energy transfer, the varied emitted color of the phosphors from blue-violet through white and finally to yellow can be achieved by properly tuning the ratio of Ce3+Eu2+. Results indicate that the present phosphor BaSiO3:Ce3+, Eu2+ is one of potential candidates for white light-emitting diodes based on UV light-emitting diodes (LEDs) chip.
