摘要：
This study developed a trivalent europium ions doped barium zirconate phosphor using the sol-gel method. X-ray diffraction spectroscopy confirmed that the crystal structure of the resulting phosphor complies with that of the cubic perovskite system. Field-emission scanning electron microscopic images reveal that the morphology of the phosphor comprises irregular spheres and cubes. Finally, the excitation spectrum of the phosphor exhibits a peak located at 228.6 nm, conforming to the charge transition state. The emission spectrum shows a peak at 440.6 nm, conforming to the ⁵D₂→⁷F₁ transition, such that the proposed phosphor radiates blue light.
