Abstract

The experimental results of luminescence measurements in Ca₃Al₂O₆ : Tb showed single excitation wavelengths at 246 and 278 nm in the UV region. For the 278 nm excitation, six distinct emission peaks were found at 378, 419, 437, 447, 487 and 544 nm. Some spectroscopic parameters were calculated using CIE coordinates showing emission in the near-blue region, which may be useful for various display devices.

用于显示应用的 Tb3+ 活化 Ca3Al2O6 荧光粉的光谱分析

Ca3Al2O6 : Tb 的发光测量实验结果显示，紫外区的单一激发波长为 246 和 278 纳米。在 278 nm 的激发波长下，在 378、419、437、447、487 和 544 nm 处出现了六个不同的发射峰。利用 CIE 坐标计算出的一些光谱参数显示，该物质在近蓝区域发射，这可能对各种显示设备有用。

期刊介绍： Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
