中文摘要：

近紫外LED芯片激发单一基质荧光材料实现白光的方式不仅能够有效改善蓝光芯片与黄光组合得到白光的色纯度、显色指数，还避免了三基色荧光粉混合中蓝光光谱能量的再吸收导致其白光效率的下降及色彩还原性的变化等问题，但单一基质中通过敏化剂与激活剂离子之间能量传递实现白光的方式很难保证其具有较高的发光效率。由于锡酸盐所具有的SnO6八面体通过不同的链接方式形成的低维晶体结构表现出自激发射的特点，本项目拟通过构建适当的能量传递途径，实现低维晶体结构锡酸盐作为高效荧光材料单一基质的白光发射。通过探索低维结构调控自激发射对激活离子之间能量传递机制的影响规律，及其晶体结构的调整致其对于激发光吸收效率变化的研究，进一步揭示基质材料结构变化对于单一基质荧光材料发光效率的影响机制。本项目的实施不仅有助于认识材料基质的结构与光活性离子发光效率的规律，而且对于白光LED荧光材料的开发及应用具有重要的理论价值和现实意义。
