Abstract

Radio-frequency (RF) magnetron sputtering was used to deposit amorphous tellurite thin films from glassy targets from TeO₂–ZnO–Na₂O/BaO/Bi₂O₃ system doped with 2.5 mol% of Er₂O₃. The impact of the sputtering power on the optical, luminescence, and structural properties of the films is discussed. The deposition process leads to amorphous and transparent films which emit light in the visible and near-infrared confirming the presence of Er³⁺ in the films’ network. Owing to their large refractive index and stability overtime, the Bi containing films are potential materials for integrated photonics and optical switches.

Er3+掺杂非晶碲薄膜

采用射频磁控溅射技术，在掺有2.5 mol% Er2O3的TeO2-ZnO-Na2O /BaO/Bi2O3体系的玻璃靶上沉积非晶碲酸盐薄膜。讨论了溅射功率对薄膜光学、发光和结构性能的影响。沉积过程产生了非晶透明薄膜，在可见光和近红外波段发光，证实了Er3+在薄膜网络中的存在。由于其大折射率和稳定性，含铋薄膜是集成光子学和光开关的潜在材料。

期刊介绍： The Journal of the American Ceramic Society contains records of original research that provide insight into or describe the science of ceramic and glass materials and composites based on ceramics and glasses. These papers include reports on discovery, characterization, and analysis of new inorganic, non-metallic materials; synthesis methods; phase relationships; processing approaches; microstructure-property relationships; and functionalities. Of great interest are works that support understanding founded on fundamental principles using experimental, theoretical, or computational methods or combinations of those approaches. All the published papers must be of enduring value and relevant to the science of ceramics and glasses or composites based on those materials. Papers on fundamental ceramic and glass science are welcome including those in the following areas: Enabling materials for grand challenges[...] Materials design, selection, synthesis and processing methods[...] Characterization of compositions, structures, defects, and properties along with new methods [...] Mechanisms, Theory, Modeling, and Simulation[...] JACerS accepts submissions of full-length Articles reporting original research, in-depth Feature Articles, Reviews of the state-of-the-art with compelling analysis, and Rapid Communications which are short papers with sufficient novelty or impact to justify swift publication.
