In order to research a new-type of red phosphors and improve its emiss ion intensity,a series of red phosphors Ca0.88－xZnx MoO₄:0.08Eu³⁺(x =0.0%,5%,10%,15%,20%,30%,40%, 50%,60%,80%) are prepared by the high temperature solid-state method,and the effects of co-doping ions concentration on crystal structure,excitation and emission prope rties of the phosphors are investigated by X-ray diffraction,excitation and emission spectr um,respectively.The results indicate that the crystal structure of calcium molybdate is changed when the co ntent of Zn is 20%,and when the content of Zn is 15%,the emission intensity of t he red phosphors is the maximum.The excitation spectrum of Ca0.88－xZnxMoO₄:0.08Eu³⁺ consists of a broad band around 200－350nm originating from the charge migration of Mo-O.The absorption peaks located at 395nm and 465nm correspond to the ⁷F₀→⁵L₆ and ⁷F₀→⁵D₂ transitions of Eu³⁺.The characteristics show that they can be effectively excited by near ultraviolet and blue chips.
