摘要：

In this work, we report on the sol-gel synthesis of red-phosphors [NaxGd1-x/3-zEuz]MoyW1-yO4 powders doped with several dopants and its luminescence properties at room temperature. X-ray diffraction patters indicated that red-phosphors powders present tetragonal symmetry and cubic structure. The red-phosphors [NaxGd1-x/3-zEuz]MoyW1-yO4 powders doped exhibit characteristic of a ultraviolet visible-light emission diode. The SEM images for [Na0.9Gd0.62Eu0.043+]Mo0.4W0.6O4 phosphor exhibits irregular morphology and cottonlike shape. The size of the particles is estimated to be about 1 mu m. Luminescence properties showed that the maximum emission in red region lies in the arrange of 613 nm and 617 nm. (C) 2010 Elsevier B.V. All rights reserved.
