Abstract

Eu3+ activated Ca9Al(PO4)7:xEu3+(CAlP:xEu3+) samples were prepared in the present work. This compounds were prepared in different concentrations of Eu3+  by combustion synthesis. Photoluminescence and CIE Colour co-ordinates characterization were studied. Data of excitation spectra reveal that the energy band from 380 nm to 410 nm appears at high intensity. The highest luminescence emission intensity found at 1 mole% of Eu3+ . A concentration of one mole percent Eu3+ ions was found to be optimal, and red light is emitted from the phosphor which is located at (0.677,0.322) in CIE coordinates.. As CAlP:xEu3+ provides red emission which helps in solving colour rendering index.
