The photoluminescence excitation and emission spectra of BaSO Cl :Ce phosphor were investigated. Excitation wavelength was 323 nm. The phosphor was prepared using a combustion synthesis method. The emission spectrum exhibited a well defined asymmetric band with a maximum at 445 nm for higher emission concentrations. The prepared samples were characterized by X-ray diffraction, scanning electron microscopy, photoluminescence and Commission Internationale de l'éclairage colour coordinates; emission intensity was related to relative Ce concentration. These developments enabled the rapid and energy-efficient production of fine particles in the powder form with little expenditure. No additional emission band was observed in the emission spectra, demonstrating that the Ce ion occupied one category of site in the prepared host phosphor.
研究了 BaSOCl：Ce 荧光粉的光致发光激发和发射光谱。激发波长为 323nm。荧光粉采用燃烧合成法制备。发射光谱显示出一个具有明确不对称带的光谱，在较高的发射浓度下，最大发射峰位于 445nm。通过 X 射线衍射、扫描电子显微镜、光致发光和国际照明委员会颜色坐标对制备的样品进行了表征；发射强度与相对 Ce 浓度有关。这些发展使得能够以很少的支出快速高效地以粉末形式生产出精细颗粒。在发射光谱中没有观察到额外的发射带，这表明 Ce 离子占据了制备的基质荧光粉中一类的位置。
