Synthesis of Long Afterglow Luminescent Materials in Silicate System

硅酸盐是一种性能稳定的基质材料。本文综述了硅酸盐体系长余辉的发展历史,制备方法和发光机理等方面的最新进展。指出了目前该类材料研究中存在的问题,并提出从基质材料、制备技术和稀土离子发光机制入手是长余辉发光材料今后研究与开发的发展方向。

Silicate was good for matrix material. The latest developments of long afterglow silicate system of the developing history, preparation methods and light-emitting mechanism were introduced. Existent problems in the system of such materials were pointed out and the future development direction of the long-lasting materials was proposed from the following directions： matrix materials, preparation methods and the light-emitting mech- anism of rare earth ions.
