A novel orange-red emitting phosphors Ca3-xEuxSi 2O7 (x = 0 - 0.03, in steps of 0.05) have been synthesized. All the compositions show orange-red emission and the emission intensity is found to be maximum for Ca2.985Eu0.015Si 2O7 [∼1.2 Vs CaS:Eu2+ (λ exe = 400 nm)]. Ca2.985 Eu0.015Si 2O7 could find potential application as orange - red phosphors for white LEDs.
