中文摘要：
采用高温固相法制备了LiSrBO3：xEu3＋荧光粉,并通过X射线衍射,红外和荧光光谱等对其表征.结果表明,LiSrBO3：Eu3＋荧光粉可被波长为395nm的紫外线和466nm的蓝光有效激发,且发射主波长为612nm（Eu3＋的电偶极跃迁5D0→7F2）的红光.研究了Eu3＋掺杂浓度对LiSrBO3：Eu3＋材料发光强度的影响,Eu3＋掺杂浓度为6%时样品的发射强度最大,并且证实Eu3＋之间的能量传递机制为电偶极子-电偶极子相互作用.Li＋,Na＋,K＋作为电荷补偿剂的引入全部导致LiSrBO3：Eu3＋材料发射强度增强,其中,Li＋的引入要优于Na＋和K＋.少量Al3＋的掺杂降低了Eu3＋所处格位的对称性,增强了Eu3＋的612nm的电偶极发射,改善了LiSrBO3：Eu3＋红色材料的色纯度.
英文摘要：
LiSrBO3：xEu3＋ phosphors were synthesized by conventional solid-state reaction and were systematically characterized by powder X-ray diffraction,Fourier transform infrared spectroscopy and photoluminescence spectroscopy.The excitation and emission spectra reveal that the LiSrBO3：Eu3＋ phosphor can be effectively excited by ultraviolet（395 nm）and blue（466 nm）light and exhibits a satisfactory red performance which peaked at around 612 nm corresponding to the 5D0 → 7F2 transitions of Eu3＋.The concentration quenching mechanism was verified to be a dipole-dipole interaction.The dopant R＋（R＋ = Li＋,Na＋ and K＋）as charge compensator can further enhance luminescence intensity,and the emission intensity of the phosphor doped with Li＋ is higher than that doped with Na＋ or K＋.Introduction of Al3＋ reduced the symmetry of the crystal field and increased the emission of 612 nm（5D0 → 7F2）,which improved the chromaticity coordinates of LiSrBO3：Eu3＋ phosphor.
