OXIDE STANNATE LUMINESCENT MATERIALS AND PREPARATION METHODS THEREOF

摘要

Luminescent materials and preparation methods thereof are provided. The said luminescent materials are represented by the following chemical formula: Ln2-xEuxSn2O7, wherein Ln is selected from one of Gd, Y or La, 0.1=x=1.5. The said luminescent materials have good electrical performance, anti-electron bombardment and stable luminescent property. It is appropriate to be used in field emission light-emitting devices. The said preparation methods have simple technique, no pollution, manageable process conditions, low preparation temperature and low equipment requirement, and are beneficial to industry production.
