Summary:Abstract Here synthesis and photoluminescence (PL) investigation of MgPbAioOi 7:Eu 3and Dy 3 carried out using combustion synthesis method. The structural and morphological studies and confirmation of phase and purity were done using XRD and SEM. PL spectra of Eu 3 doped sample showed peaks corresponding to the 5Do-7Fj ( =1,2,3&4) transitions showing emission at 592nm (yellow) with another at 618 nm(red) for excitation at 396 nm, while in case of Dy3 showing emission at 484nm (blue) and 574 nm(yellow) for 350 nm excitation showing strong and prominent emission for the generation of white light.
