Blue-Greenish Light Emission from Stress-Activated SrCaMgSi2O7(:)Eu

摘要：

　　We have revealed that SrCaMgSi2O7(:)Eu phosphors emits blue-greenish light under the application of a mechanical stress,called as mechanoluminescence (ML).The ML showed a similar spectrum as photoluminescence,which indicated that ML is emitted from the same center of Eu2+ ions as PL.Such a blue-greenish light of ML emission can be seen by the naked eye when pressing the sample.In addition,the ML intensity of SrCaMgSi2OT(:)EU proportionally increased with the increase of mechanical load.
