| 中文摘要 | Red-emitting Li2Sr1-3x/2EuxSiO4 0 <= x <= 0.5) phosphors were synthesized at 900 degrees C in air by a solid-state reaction. The synthesized phosphors were characterized by X-ray powder diffraction, photoluminescence (PL) excitation (PLE) and PL spectra. The results from the PLE spectra suggest that the strong 394 nm excitation peak associated with the L-5(6) state of Eu3+ ions is of significance for near ultraviolet pumped white light-emitting diodes and solid-state lighting. It is also noted that the position of the charge transfer state of Eu3+ ions shifts towards the higher energy side (blue shift) by increasing the content of Eu3+ ions. The predominant emissions of Eu3+ ions under 394 nm excitation are observed at 580, 593, 614, 656 and 708 nm, which are attributed to the D-5(0) -> F-7(J) (J = 0, 1, 2, 3 and 4), respectively. The PL results reveal that the optimal content of the red-emitting Li2Sr1-3x/2EuxSiO4 phosphors is x = 0.475. Simulation of the white light excited by 394 nm near ultraviolet light has also been carried out for its potential white light-emitting diode applications.
