Di-barium magnesium silicate doped with Eu and Tm phosphors were prepared for different concentrations of Tm ions keeping the concentration of Eu as 0.5 mol%. Photoluminescence (PL) studies of prepared samples were carried out. Emission spectra exhibited optimum green color emission at 509 nm when Tm was 1.5 mol%. Emission is expected to arise due to the transition of Eu...
