以CaCO3(99.9%)、Li2CO3(99.9%)、Na2CO3(99.9%) K2CO3(99.9%)、H3BO3(99.9%)、Sm2O3(99.9%)为原料，按所设计的化学计量比称取以上原料，在玛瑙研钵中混合均匀并充分研磨，装入刚玉坩埚，采用固相法制备LiCaBO3∶Sm3+材料；通过美国XRD6000型X射线衍射仪和日本岛津RF-540荧光分光光度计对材料的性能进行表征，所有测量均在室温条件下进行。LiCaBO3∶Sm3+材料的发射光谱由三个橙红色发射峰组成，主峰位于561，602，651 nm，分别对应Sm3+的4G5/2→6H5/2、4G5/2→6H7/2 和4G5/2→6H9/2跃迁；监测602 nm发射峰，得到其激发光谱由320~420 nm的宽激发带组成。由激发和发射光谱看出，LiCaBO3∶Sm3+能够有效地被紫外LED芯片激发，发射红色光。研究了Sm3+浓度(x)对LiCa1-xBO3∶xSm3+材料发射强度的影响，结果表明：随Sm3+浓度的增大，发射强度先增强后减弱，Sm3+掺杂摩尔分数为3%时，发射强度最大，依据Dexter理论，计算得出其浓度猝灭机理为电偶极-偶极相互作用。掺入电荷补偿剂Li+、Na+和K+均提高了LiCaBO3∶Sm3+材料的发射强度。

LiCaBO3∶Sm3+ phosphor was synthesized by solid state reaction and its luminescent properties were studied. The emission spectrum consists of three major orange-red emission bands at 561, 602 and 651 nm, which correspond to the 4G5/2→6H5/2, 4G5/2→6H7/2 and 4G5/2→6H9/2 typical transitions of Sm3+, respectively. The excitation spectrum for the strongest emission (602 nm) extends in 320~420 nm, which indicated that this phosphor can be effectively excited by near-ultraviolet light-emitting diodes. The influences of Sm3+ concentration (x) on the emission intensity of LiCa1-xBO3∶xSm3+ phosphors were also investigated. The results showed that the intensity increases with increasing Sm3+ concentration, then decreases, and reaches the maximal value at 3% Sm3+. And the concentration self-quenching mechanism is the d-d interaction according to Dexter theory. The emission intensity of LiCaBO3∶Sm3+ can be enhanced by doping charge compensator Li+, Na+, K+.
