After John wrote the abstract "红色荧光粉一直是发光材料领域研究的热点,硼酸盐红色发光材料具有稳定性好、合成容易等优点,越来越引起人们的关注.采用固相法在还原性气氛下制备了(Sr3xEux)B2O6东列红色荧光粉.荧光粉能被393nm和464nm的光有效激发,发射主峰位于606nm的红光,当铕离子的摩尔掺杂量为0.07时发光强度最大.用少量BaF2进行助溶时,有利于在较低的烧结温度下获得发光强度更高的荧光粉.", he wrote these keywords "双坩埚法, (Sr3-xEux)B2O6, 东列". Do you think his choice of keywords was correct? Answer yes or no.
