摘要

在 850°C 的高温空气中合成了 K2-xPbxAl2B2O7 (0.0025 ≤ x ≤ 0.03) 紫外线发光荧光粉。粉末 X 射线衍射技术用于分析所有制备的硼酸盐的相。傅立叶变换红外技术用于检测 K2Al2B2O7 的键结构。在室温下,使用分光荧光仪检测制备的荧光粉的光致发光特性。结果发现,K2Al2B2O7:Pb2+ 的发射带和激发带分别位于 373 纳米和 271 纳米。对 K2-xPbxAl2B2O7 的发射强度与 Pb2+ 含量之间的相关性进行了广泛的研究。结果发现,0.01 摩尔 Pb2+ 是 K2Al2B2O7 中的最佳浓度。最终发现,制备的材料 K2Al2B2O7:Pb2+ 的斯托克斯位移为 10,090 cm-1,激发波段为 271 nm,发射波段为 373 nm。这项研究的结果是建立了一种全新的 UVA 辐射发射材料。

Synthesis and Photoluminescence Properties of Pb2+-Doped K2Al2B2O7

Ultraviolet-emitting phosphors with the formula K2–xPbxAl2B2O7 (0.0025 ≤ x ≤ 0.03) were synthesized at 850°C for 6 h in air. The powder X-ray diffraction technique was used to analyze the phases of all prepared borates. The FTIR technique was used to examine the bond structure of K2Al2B2O7. At room temperature, a spectrofluorometer was used to examine the photoluminescence characteristics of the prepared phosphors. K2Al2B2O7:Pb2+ was found to have emission and excitation bands at 373 and 271 nm, respectively. An extensive investigation was conducted on the correlation between emission intensity and Pb2+ content for K2–xPbxAl2B2O7. Consequently, 0.01 mol Pb2+ was found to be the optimal concentration in K2Al2B2O7. Eventually, it was found that the Stokes shift of the prepared material K2Al2B2O7:Pb2+ is 10,090 cm−1 using the excitation band at 271 nm and the emission band at 373 nm. As a result of this investigation, a brand-new UVA radiation-emitting material has been established.
