摘要

Novel Li0.9Y(0.9-x-y)Zr0.1O2:Eu-x(3+), R-y(3+) (R = Ce, Bi) red nanocrystal phosphors were synthesized by the sol-combustion process at 800 degrees C. XRD and TEM were used to evaluate the crystallinity and the morphological characterization of the samples. The photoluminescence properties and lifetime of the obtained phosphor nanoparticles were measured using an Edinburgh FLS920 at room temperature. The result showed that the luminescence intensity of Li0.9Y(0.9-x-y)Zr0.1O2:Eu-x(3+) was increased by Bi3+ and Ce3+ by 900% and 600%, respectively. The emission mechanism and sensitization mechanism of Bi3+ and Ce3+ on EU3+ emission intensity were described and explained in detail in this work. The high bright and color-uniform fluorescence images of the doped samples with short luminescence decay times (nanosecond level) confirmed the potential applications of the phosphors in light-emitting diodes and display devices.
