A promising candidate of purple blue Ca2MgSi2O7: Ce3+ phosphor sample was successfully fashioned via high temperature solid-state reaction technique and characterized in terms of structural, morphological, optical and thermal properties using XRD, FESEM, EDX, FTIR, PL, TL properties including with CIE chromaticity diagram. The results of the powder XRD patterns clearly informed that this sintered crystal structure demonstrates tetragonal crystallography (i.e., akermanite phase structure) with a space group (i.e., P¯421m). The average crystallite size (D) is calculated to be about 70nm. The actual formation and absorption of different functional groups was well clarified by FTIR. The PL emission spectra show the 5d-4f allowed transition of Ce3+ ions. This phosphor is a promising candidate of long persistent mechanism because the activation energy (i.e., trap depth) of the sintered sample was obtained in the range between (1.27eV-1.69eV). It can also be applicable in high temperature dosimetry applications. The favorable features for applications likewise near UV-LED conversion phosphor, white light emitting diodes (WLEDs), long-persistent afterglow properties, solid-state lighting devices, drug delivery, tissue engineering, bone material, detection of cancer disease, DNA transplantation, and Image processing of computer science etc.
