Abstract: A variety of inorganic compounds known as silicates has grown to be more popular as a result of their superior chemical resistance and transparency to visible light, which make them suitable for a wide range of uses. They are more expressively researched because to their excellent thermal and chemical stability, inexpensive price, and strong near-ultraviolet absorption. Ca2MgSi2O7:Eu2+, Dy3+ phosphor was synthesized by high-temperature solid-state reaction technique. This structure is a member of melilite group and revealed tetragonal, Akermanite structure with a space group P¯421m. The excitation spectrum shows a broad absorption band at 200–400nm with 365nm wavelength single broad emission peak situated at 505nm was obtained. The prepared Ca2MgSi2O7:Eu2+, Dy3+ phosphors were characterized using photoluminescence excitation and emission spectra. Prominent green colour emission was obtained under ultraviolet excitation.
