Sral2O4: EU2Dy3Of Pressure Sensitive afterglow luminescence Performance Study

Di Hou

Abstract


This paper on Long Afterglow MaterialSral2O4: EU2Dy3In low gas pressure(0 ~ 300000 PA)Hold up a of afterglow strength changes the system to studyFound for same of Gas PressureAfterglow brightness of response situation with pressure time point of change differentAnd in100 ~ 260 sBetween sensitivity with the start time of delay and increaseHas is good regularity.In0 ~ 300000 PaPressure range inSral2O4: EU2Dy3Of afterglow strength change situation and gas pressure change value linear related and sensitivity is high.We thinkSral2O4: EU2Dy3As an new pressure sensitive luminescence material in non-contact pressure field has good of Application Prospect.
