Synthesis, X-ray diffraction and photoluminescence investigations of Eu 3+ -doped SrBPO 5 phosphor has been carried out in order to characterize the material. PL emission spectrum of air heated SrBPO 5 :Eu 3+ phosphor exhibits bands at 590, 614, 651 and 702nm under 238nm excitation, assigned to the 5 D 0 → 7 F J (J=1, 2, 3, 4) transitions of Eu 3+ ions. Of these transitions, the emission centered at 614nm is the most prominent. Photoluminescence decay time and Time-resolved emission spectrometric (TRES) studies of Eu 3+ were carried out with λ em =614nm and λ ex =238nm. It suggested that Eu 3+ ions are present at two different sites and predominantly occupying Sr 2+ sites in the host lattice. Judd–Ofelt intensity parameters and other radiative properties were evaluated from the emission spectrum by adopting standard procedure. The trend observed in the J–O parameters (Ω 2 >Ω 4 ) confirms the covalency exiting between the Eu 3+ ion and ligands as well as the asymmetry around the metal ion site. The color coordinates of the system were evaluated (x=0.558 and y=0.355) and plotted on a standard CIE index diagram. The observations showed that the SrBPO 5 :Eu 3+ phosphor is very close to the red emission material. Photoluminescence intensity was compared with that of a commercial red phosphor for commercial utility purpose. It is observed that, the photoluminescence intensity of the prepared phosphor was 60% as compared to the commercial phosphor Y 2 O 3 : Eu.
