AB - SrAl2O4 : Eu 2+ ,Dy 3+ phosphorescent phosphors were synthesized by skull melting method. The molar ratio of oxides in the phosphors synthesized by the skull melting technique was SrCO3 : Al(OH)3: Eu2O3: Dy2O3= 1 : 2 : 0.015 : 0.02. Crystal structure and surface morphology were investigated by scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis. Optical properties of the synthesized SrAl2O4: Eu 2+ ,Dy 3+ were measured by photoluminescence (PL) spectrometer for in-depth study on the excitation, emission and afterglow properties. From the PL measurements, it was found that excitation occurred in the wavelength range from 300 to 420 nm with peak position at 360 nm. The emission spectrum showed a broad curve in the wavelength from 450 to 600 nm with peak position at 530 nm. SrAl2O4: Eu 2+ ,Dy 3+ phosphors exhibited afterglow properties with emission that lasted for a long period.
