The luminescent properties of the new red phosphors in the solid solution system CaxCd1-xMoO4:Eu3+, Li+ are reported. Their dominating emission peaks are at 615 nm, which satisfies color purity. Under the excitation of similar to 320 nm UV light, some selected samples have luminescent intensity 30% higher than that of the commercial red phosphor Y2O2S:Eu3+. Therefore, it is a promising material for N-2 plasma display application. (c) 2005 The Electrochemical Society. All rights reserved.
