Thermoluminescence and Mechanoluminescence Properties of Ba2-xMgSi2O7:XCe3+ Phosphors

The Ce3+ doped Ba2MgSi2O7 phosphor is synthesized via high temperature solid state reaction method. The Thermoluminescence (TL) and Mechanoluminescence (ML) analysis presents that the emission of this phosphor is in violet region around 400 nm. It is found that the TL intensity is maximum for 0.05mole Ce3+doping and the TL intensity increases with UV exposure time up to 25 min then decreases for higher UV radiation dose. The ML intensity of Ba2MgSi2O7:Ce3+ is maximum for 0.05 mole Ce3+ doping and it is also observed that ML intensity is increasing approximately linearly with impact velocity.
