目前国内外对各种红色荧光材料的合成已开展了较多的研究工作,许多材料目前绝大多数还处于实验室研究阶段,不能真正形成产业化,且许多材料普遍存在着稳定性差,合成路线复杂,且处于近紫外激发,需要的能量高。特别是目前绿色能源的大力提倡,越来越多的人开始注重节能和环保,这就要求大力开发节能和环保的绿色产品。用氨水沉淀法合成的Ca2-xEuxSnO4荧光材料,激发范围在长波紫外激发区域,激发所需的能量是非常低的,而且原材料也要便宜很多,更有益于实现红色荧光材料的商业化。
At present, more and more researches have been done on the synthesis of various red fluorescent materials at home and abroad. At present, most of the materials are still in the laboratory research stage and can not really be industrialized. Many materials generally have poor stability and synthetic routes Complex, and in the near-ultraviolet excitation, high energy requirements. In particular, the current strong advocacy of green energy, more and more people began to focus on energy saving and environmental protection, which requires vigorously develop energy-saving and environmentally friendly green products. The Ca2-xEuxSnO4 fluorescent material synthesized by ammonia precipitation has a very low energy required for excitation in the long-wave UV excitation region, and the raw materials are much cheaper and more beneficial for the commercialization of red fluorescent materials.
