phosphor shows the improved white light by shifting towards the warm white region. The energy transfer from Dy

to Eu

ions is investigated by means of PL intensities. The luminescence intensities and chromaticity coordinates can be modified by controlling the concentration and the ration of doping Dy

and Eu

. The calculated chromaticity coordinates indicate that Ba
