摘要：

Red phosphors with compositions of Li2+xNb3xTi1-4xO3:3 wt.% Eu3+ (0.01 <= x <= 0.08) were synthesized by solid-state reaction method. The samples were investigated by using X-ray diffraction (XRD) and photoluminescence spectroscopy, respectively. XRD results showed that all samples were main phase of Li2TiO3. Emission spectra of Li2+xNb3xTi1-4xO3:3 wt.% Eu3+ powders showed strong red emission at 612 nm (D-5(0)-F-7(2)) with 396 nm excitation. In addition, the excitation and emission intensity increased up to x = 0.06, and then decreased with further increasing of the x values. And the chromaticity coordinate (CIE) of the component with x = 0.06 was superior to other components.
