Abstract

This paper presents the results of an investigation of the electrical, dielectric, ferroelectric, and second-order nonlinear optical properties of SrB4O7 synthesized by methods of both solid-state reaction (SSR) and crystallization of a glass tape (GT). To obtain GTs of SrB4O7, the melt consisting of appropriate precursors was rapidly cooled using a twin-roller. The prepared GTs were crystallized at 730°C for different durations and analyzed by X-ray diffraction. The formation of “extended” crystals in the central part of GTs due to the application of the GT technology is discussed. The investigation of the current-voltage characteristic of the sample prepared by SSR showed that its breakdown voltage is higher than 1000 V. The measurements of the dielectric parameters in the frequency range of 1 KHz–1 MHz showed that the dielectric constant is about 7.5, and the dielectric loss varies from 0.002 to 0.0008. These parameters are sufficiently stable in the temperature range from room temperature to 150°C. The ferroelectric properties of the GT crystallized at 730°C for 3 h were also investigated. At 20 kV/cm, a remnant polarization of 0.18 μC/cm2 was measured. Optical measurements showed that the intensity of second-harmonic generation in the GT crystallized at 730°C for 3 h is 5.4 times higher than that of KH2PO4 (KDP).

玻璃带中 SrB4O7 的结晶及其电气、介电、铁电和非线性光学特性

本文介绍了通过固态反应（SSR）和玻璃带结晶（GT）两种方法合成的 SrB4O7 的电学、介电、铁电和二阶非线性光学特性的研究结果。为了获得 SrB4O7 的玻璃带，使用双辊快速冷却由适当前体组成的熔体。所制备的 GT 在 730°C 的温度下结晶，持续时间各不相同，并通过 X 射线衍射进行分析。讨论了由于 GT 技术的应用而在 GT 中心部分形成的 "扩展 "晶体。对 SSR 制备的样品的电流-电压特性的研究表明，其击穿电压高于 1000 V。对频率范围为 1 KHz-1 MHz 的介电参数的测量表明，介电常数约为 7.5，介电损耗在 0.002 至 0.0008 之间。这些参数在室温至 150°C 的温度范围内足够稳定。此外，还研究了在 730°C 下结晶 3 小时的 GT 的铁电特性。在 20 kV/cm 的电压下，测得残余极化为 0.18 μC/cm2。光学测量结果表明，在 730°C 晶化 3 小时的 GT 中产生的二次谐波强度是 KH2PO4（KDP）的 5.4 倍。

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.
