通过研究各种添加剂如铕（Eu）、铝（Al）和钙（Ca）对基于氧化硼的磷光体的光致发光性能的影响，已经制备并研究了新的红色发光磷光体。当同时加入Eu和Ca离子时，可以通过使用液体前体的简单过程来合成Ca3B2O6：Eu磷光体。在254nm激发下，Ca3B2O6：Eu荧光粉在611nm处发出红光，当Eu离子浓度为0.13M时，荧光粉的内量子效率达到41.5%。
New red-emitting phosphors have been produced and studied by investigating the effects of various additives such as europium (Eu), aluminum (Al), and calcium (Ca) on the photoluminescence performance of boron oxide-based phosphors. When both Eu and Ca ions were added, Ca3B2O6:Eu phosphors could be synthesized via a straightforward process using a liquid precursor. The photoluminescent spectra of Ca3B2O6:Eu phosphors exhibited a red emission at 611nm under 254nm excitation, and the internal quantum efficiency reached 41.5% when the concentration of Eu ion was fixed at an optimal condition of 0.13M.
