The luminescence properties of a newly prepared Cd2P6O7: Tb inorganic phosphors, prepared first time by economical, simple and time saving slow vaporization synthesis technique are discussed. The structure of this prepared phosphor is characterized by using X-Ray diffraction. FTIR characteristics of the phosphor is also carried out. The photoluminescence (PL) measurement is carried out. It shows our sample exhibit emission with peaks at 488 nm, 534 nm and 550 nm corresponding to the transitions of Tb ion. The excitation spectra monitored at 550 nm shows broad intense excitation band at 236 nm. The phosphor shows CIE 1931 color coordinates as blue (x= 0.05466, y= 0.25409) and yellow (x= 0.3016, y= 0.6923) which combines to give white light. The phosphor is well suited for White light emitting diodes (WLED) applications.
