| Abstract: | Using NH4HCO3-NH3·H2O as mixed precipitator,(Ca1-x-yLuy)MoO4:xEu3+ red phosphors were synthesizedby co-precipitation method.The phase formation,composition and luminescence properties of(Ca1-x-yLuy)MoO4:xEu3+ were analyzed by XRD,EDS,PL and CIE.The results show that(Ca1-x-yLuy)MoO4:xEu3+ red phosphors have been successfully prepared by co-precipitation method according to theoretic ratio,and the synthesized(Ca1-x-yLuy)MoO4:xEu3+ have scheelite structure with pure phase.The phosphors have strong electron absorbability of 7F0→5L6 and7F0→5D2 at 394 nm and 465 nm and can emit red lighting with high intensity.The CIE of(Ca1-x-yLuy)MoO4:xEu3+ redphosphors is(0.666 5,0.332 9),which is better than that of traditional Y2O2S:Eu3+ red phosphors.In addition,whenthe concentration of Lu is 30mol%,the luminescent intensity of(Ca0.55Lu0.3)MoO4:0.15Eu3+ is highest. |
