Preparation and Luminescence Properties of Na+, Li+, Bi3+ Doped CaWO4:Eu3+ Phosphors†

doi:10.7503/cjcu20170406

Abstract

Abstract:

Na⁺, Li⁺, Bi³⁺ doped CaWO₄:Eu³⁺ phosphors were synthesized by microwave-assisted heating solid state reaction method. The microstructures of the sampless were characterized by XRD and SEM. The excitation spectra, emission spectra and energy levels of the samples were detected and analyzed by fluorescence spectrophotometer. The results showed that the samples all kept the tetragonal matrix. Compared with the particle size of CaWO₄:Eu³⁺phosphor, the size of Na⁺, Li⁺, Bi³⁺ doped or codoped CaWO₄:Eu³⁺ phosphors all increased. Under 393 nm excitation, the luminescence intensities of samples doped with Na⁺ and Li⁺ are 1.8 and 1.2 times that of undoped these ions, and the luminescence intensities all decreased for the sample codoped with Li⁺, Na⁺ and the sample codoped with Li⁺, Bi³⁺. Under 254 and 393 nm excitation, the lifetime of the sample doped with Li⁺ was the shortest in all samples. For the same sample, the energy level lifetime under the 393 nm excitation was shorter than that under the 254 nm excitation.

Key words: Microwave-assisted heating method, CaWO4:Eu3+, Luminescence property, Energy level lifetime
