Dysprosium doped di-strontium magnesium di-silicate white light emitting phosphor by solid state reaction method
The phase structure of the Sr2MgSi2O7:Dy3+ phosphor is consistent with standard tetragonal crystallography. CIE color coordinates of Sr2MgSi2O7:Dy3+ are suitable as white light emitting phosphor. Decay graph indicate that this phosphor also contains fast decay and slow decay process. ML intensity increases linearly with increasing impact velocity of moving piston.
