Abstract

Sr2MgSi2O7:Eu2+, Dy3+ and Ca2MgSi2O7:Eu2+, Dy3+ phosphors were synthesized by the high-temperature solid-state reaction method. The phase structure of the prepared phosphors was of akermanite type, which belongs to the tetragonal crystallography. The EDX and FTIR spectra confirm the presence of elements in prepared phosphors. Sr2MgSi2O7:Eu2+, Dy3+ and Ca2MgSi2O7:Eu2+, Dy3+ phosphors would emit blue and green light; the main emission peaks that appeared at 465 and 535 nm belong to the broad emission band ascribed to the 4f65d1 → 4f7 transition. Decay graph indicates that both the phosphors have fast decay and slow decay. Investigation into afterglow property showed that the Sr2MgSi2O7:Eu2+, Dy3+ phosphor held better afterglow property than Ca2MgSi2O7:Eu2+, Dy3+ phosphors. ML measurements showed a linear increase in the ML intensity with the impact velocity of the moving piston.
