Blue emitting KBaPO4: Ce3+ phosphors sample is prepared using combustion synthesis method. Spectroscopic properties of Ce3+ and integrate the Ce3+ ion with host inorganic material show interest for most of the applications in photoluminescence studies. Prepared sample of KBaPO4: Ce3+carried out for emission and excitation spectra for photoluminescence measurement. XRD, morphology, absorption band and concentration of Ce3+ ion with emission intensity are reported in present work. Structural and morphological studies confirm phase and purity of prepared sample with crystalline in nature. PL spectra of Ce3+ due to the 4f–5d transition of Ce3+ ions peaking at 330 nm. Chromatic properties index with the help of the emission spectra with color coordinate of sample observed in blue region. The photoluminescence emission spectra of KBaPO4: Ce3+ phosphor exhibit blue emission band centered at 440 nm.
