A series of molybdate phosphors doped with Zn²⁺,Mg²⁺,Ba²⁺ and activated by Eu³⁺ were prepared by the high temper ature solid-state method.The phosphors′ phase structure and luminescence pr operties are analyzed by testing their emission spectra,excitation spectra,X-ra y diffraction (XRD) and so on.The experimental results show that the phosphors c an be excited by n ear-UV (395nm) and blue (465nm) light and emit red light at 616nm (⁵D₀→⁷F₂ transition of Eu³⁺).The 395nm and 465nm excitation wavelengths are suitable for LED manufacturing.The luminous intensities of the red phosphors Ca0.88－xRxMoO₄:0.08Eu³⁺ doped with Zn²⁺,Mg 2+,Ba²⁺ are improved,and the optimal doping comcentrations are 15% ,10% and 5%,respectively.The order of the three red phosphors′ luminous intensi ties is Ca0.73 Zn0.15 MoO₄:0.08Eu³⁺> Ca0.78 Mg0.10 Mo O₄:0.08Eu³⁺> Ca0.83Ba0.05 MoO₄: 0.08Eu³⁺ with their optimal concentrations.The chromaticity coordinates of the phosphors are up to the national standard,so those red-emitting materials s how good potential of the red commercialization phosphors.
