In the present work Li4-xMoO5:xEu3+ (x=0.01, 0.03, 0.05 & 0.07) novel phosphors are prepared using Combustion synthesis method and their luminescent properties were investigated. The excitation spectra consist of broad charge transfer bands in the short-wave UV region of Mo6+→O2- and Eu3+→O2- with two sharp lines around 395nm and 465nm of the Eu3+ 4f excitation transitions. The results indicated that the characteristic emissions of MoO4 are quenched absolutely and phosphor exhibited intense red photoluminescence at 617 nm when excited by the light of 395nm, which was attributed to the electric dipole energy transition of 5D0→7F2 transition of Eu3+. The optimal doping concentration for Eu3+ ions is found to be 3 mol% and the quenching mechanism is attributed to the dipole-dipole interaction.In the present work Li4-xMoO5:xEu3+ (x=0.01, 0.03, 0.05 & 0.07) novel phosphors are prepared using Combustion synthesis method and their luminescent properties were investigated.

A simple wet chemical synthesis of Eu2+ activated Ca5(PO4)3Br and Ca5(PO4)3I phosphors and their photoluminescence is reported. Formation of Ca5(PO4)3Br is confirmed by X-ray diffraction (XRD). Synthesized phosphors are analyzed for photoluminescence (PL) spectrum. A bright blue emission is observed when phosphors are excited by near Ultra Violet (nUV) radiations. Photoluminescence emission spectrum for (Ca0.985Eu0.015)5(PO4)3Br is centered at 457 nm and for (Ca0.985Eu0.015)5(PO4)3 I it peaks at 455 nm when excited by 365 nm near UV radiation. Eu2+ luminescence in Ca5(PO4)3Br is reported for the first time. The phosphors can be efficiently excited by nUV radiations. This shows that phosphors may be used as blue phosphor in pcLED for Solid State Lighting.A simple wet chemical synthesis of Eu2+ activated Ca5(PO4)3Br and Ca5(PO4)3I phosphors and their photoluminescence is reported.
