Abstract

New phosphors Ca2Mg(BO3)2: Ce3+ were synthesized by the solid-state reaction method at a high temperature. The phase purity was characterized by powder X-ray diffraction (XRD). The ultraviolet-visible (UV-Vis) optical properties of Ce3+ have been investigated, and the lowest 5d levels, the emission, and the Stokes shifts of Ce3+ in the host lattice were identified. In addition, its concentration quenching process was also studied. The results show that Ce3+ ions enter Ca2+ sites with only one emission in a UV-Vis range and that the optimum doping concentration is x = 0.05. The excitation and emission spectra were evaluated to clearly reveal luminescence features.

Ce3+在Ca2Mg(BO3)2荧光粉中的紫外可见发光及其应用前景

采用高温固相反应法制备了新型荧光粉Ca2Mg(BO3)2: Ce3+。采用粉末x射线衍射(XRD)对相纯度进行了表征。研究了Ce3+的紫外-可见(UV-Vis)光学性质，确定了Ce3+在主晶格中的最低5d能级、发射和Stokes位移。此外，还对其浓淬过程进行了研究。结果表明，Ce3+离子在UV-Vis范围内进入Ca2+位点只有一次发射，最佳掺杂浓度为x = 0.05。对激发光谱和发射光谱进行了评估，清晰地揭示了发光特征。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
