[en] The Akermanite type calcium magnesium silicate Ca₂MgSi₂O₇: Eu²⁺ activated and Ce³⁺ doped phosphor powder were prepared using high temperature solid state reaction. Their optical properties like thermoluminescence (TL), Photoluminescence (PL) were investigated in detail. Under UV irradiation, Ca₂MgSi₂O₇:Ce³⁺Eu²⁺ phosphor exhibits a prominent emission band around 466nm. The Thermoluminescence (TL) analysis observed that it has been a single glow peak was occurred in all the TL glow curves of Ca₂MgSi₂O₇: Eu²⁺,Ce³⁺ codoped phosphor. Moreover, the kinetic parameter (activation energy and frequency factors) of trap centers was calculated from the TL glow curve of the prepared sample. (author)
