Abstract

An excellent long afterglow SrCaMgSi2O7:Eu2+, Dy3+ phosphor was prepared by the high-temperature solid-state reaction method. The phase structure of prepared phosphor was an akermanite-type structure, which belongs to the tetragonal crystallography with space group $$ {\text{P}}\overline{{{\text{42}}}} _{{\text{1}}} {\text{m}} $$ P 42 ¯ 1 m . Chemical composition of the sintered SrCaMgSi2O7:Eu2+, Dy3+ phosphor was confirmed by EDX. Under ultraviolet excitation, the SrCaMgSi2O7:Eu2+, Dy3+ phosphor would emit bluish-green (cyan) light, belonging to the broad emission band ascribed to the 4f65d1 → 4f7 transition. Investigation of afterglow properties show that SrCaMgSi2O7:Eu2+, Dy3+ phosphor held a fast and slow decay process. The peak of ML intensity increases linearly with increasing impact velocity of the moving piston. The CIE chromaticity diagram and ML spectra show a similar spectrum as PL spectra, which indicated that ML is emitted from the same emitting center of Eu2+ ions. Thus the present investigation indicates that the piezoelectrically induced de-trapping model is responsible to produce ML in prepared SrCaMgSi2O7:Eu2+, Dy3+ phosphor.
