摘要：

By sol-gel method, (Ca-0.54, Sr-0.34)(Mo-0.2. W-0.8)O-4: Eu-0.08(3+) luminescent materials can be synthesized. X-ray diffraction analysis indicates that it owns tetragonal scheelite structure, belonging to l-center with space group 14(1)/a [88], Z=4. The emission spectra, excitation spectra and fluorescence decay curves are measured, and the partial Judd-Ofelt parameters and, under 395 nm excitation, quantum efficiency of Eu3+ D-5(0) energy level are calculated. The results indicate that Eu3+ D-5(0)-F-7(2) red luminescence can be excited by 395 nm, 465 nm and 535 nm in the hosts, respectively, and its quantum efficiency can be improved in space and it has potential application for white light emitting diodes as the red luminescent materials.
