Rare earth luminescent material CaAlSiN3:Eu2+ (CEu) was applied and modified with (3-Aminopropyl) triethoxysilane (KH550) to obtain two types of rare conversion agents, CEu KH550-modified (KCEu). Two kinds polylactide (PLA) films were successfully prepared through solution blending. The results showed that the addition complex increases crystallinity PLA. More importantly, both PLA/CEu PLA/KCEu...
