Abstract: In this paper, the synthesis and the luminescence properties of Eu3+-CaMoO4 nono-materials were described. With different reaction temperature, the same reaction time, and the different concentration of Eu3+, we produced a series of samples which have different Eu3+ concentration by hydrothermal method. XRD, TEM, FL were used to characterized the phases, morphologies, luminescence properties of the products. In result, the crystallinity and luminescence intensity became better with increase of the reaction temperature, it is the best property of 3%-Eu3+-CaMoO4 in 200℃ for 30h. The morphology of the products is date pit. It is presented that in 494nm, the luminescence intensity of CaMoO4 is decreased, however, in 615nm, the luminescence intensity of Eu3+ is increased which may due to the energy transfer from CaMoO4 to Eu3+.
