文章用提拉法生长出Li6Gd(BO3)3:Ce晶体,并对其光谱性能与发光过程进行了探索. 借助于真空紫外-紫外透过光谱测试,发现晶体的透过光谱中存在Ce3+离子和Gd3+的特征吸收峰,同时还存在与Ce4+离子相关的电荷迁移带. 对晶体的真空紫外-紫外激发发射光谱进行研究发现,在晶体存在着Ce3+离子的5d4f辐射跃迁发光与Gd3+离子的4f4f辐射跃迁发光,而且存在着Gd3+Ce3+之间的能量传递. 对Li6Gd(BO3)3:Ce晶体的X射线与射线激发发射光谱研究可知,晶体在高能射线激发下的闪烁光主要是Ce3+离子的发光.

Colorless and transparent Li6Gd(BO3)3:Ce crystals are grown with the Czoralski method. Their optical characteristics and luminescence processes are also investigated. The ultraviolet-vaccum ultraviolet (UV-VUV) transmittance spectra are measured and the result shows that absorption peaks due to Ce3+ ions and Gd3+ ions, and the absorption band related to charge transfer band of Ce4+ ions are present. According to the UV-VUV excitation and emission spectra, it is found that there appear luminescences of 5d4f radiative transitions of Ce3+ ions and of 4f4f radiative transitions of Gd3+ ions, and also Gd3+Ce3+ energy transfer. The X-ray and -ray stimulated luminescence spectra show that the scintillation light of the crystal is mainly from Ce3+ ions.-
