中文摘要	in our study, the eu2+ doped li2casio4 phosphors were initially synthesized by high temperature solid state method, and their luminescent properties were also investigated. eu2+ ions occupied 8-coordinatid distorted dodecahedral ca sites, leading to strong crystal field splitting. the strong crystal field splitting made the broad excitation band extending from uv to visible region. in addition, the high concentration of li+ ions in the structure constrained the distortion of the emission centers, then resulted in a small stokes shift, similar to 1100 cm(-1). under excitation, the li2casio4:eu2+ phosphors emitted bluish green light with peak of 480 nm, fwhm of 31 nm and color coordination of (0.06, 0.44). the eu2+ doped li2casio4 phosphor would be suitable for bluish green phosphor of white leds due to its excellent excitation profile and chromaticity.
