摘要

研究材料的光学特性对于进一步开发和制造光学产品至关重要。最近,作者开发出了 AgCl0.25Br0.75 - AgI 系统的单晶体和两相陶瓷。这项工作的重点是研究 AgCl0.25Br0.75 - AgI 体系材料的透射范围、折射率色散、光学损耗和光阻,并比较单晶体和陶瓷的特性。这些材料在 0.49 至 54 um 的可见光和红外区域以及 300-1500 um(0.3-1.0 THz)的太赫兹(远红外和毫米波区域)范围内都是透明的。对于所有成分,红外折射率在 2.107 至 2.436 之间变化。材料在中红外的吸收系数为 (0.06-6.67) ∙ 10-4,与已知的其他卤化物材料相比较低,表明其光学损耗较低。最后,随着 AgCl0.25Br0.75 固溶体中 AgI 含量的增加,单晶和两相陶瓷的光阻都呈上升趋势。紫外线照射后,材料在可见光和中红外(10 µm)波段的透射率下降,而在 10 µm 或以上波段的透射率损失可以忽略不计。本研究对 AgCl0.25Br0.75 中 AgI 含量为 20 摩尔%的单晶体和两个陶瓷样品的特性进行了比较。比较结果表明,陶瓷材料的折射率值接近但不完全相同,陶瓷材料的吸收系数增大,机械混合物样品的光阻较低。后两个特征与基于机械混合物的两相陶瓷的高异质性有关,这导致了功能特性的恶化。这些结果证明,这些材料在医疗技术、热成像技术和光电子技术的光纤和光子学领域具有广阔的应用前景。

Optical properties of crystals and two-phase ceramics of the AgCl0.25Br0.75 – AgI system
Research of materials’ optical properties is critical for further development and manufacturing of optical products. While recently, single crystals and two-phase ceramics of the AgCl0.25Br0.75 – AgI system have been developed by the authors. This work is focused on studying the transmission ranges, refractive index dispersion, optical losses, and photoresistance of materials in the AgCl0.25Br0.75 – AgI system, as well as comparing the properties of single-crystals and ceramics. The materials are transparent in the visible and IR regions from 0.49 to 54 um, as well as in the terahertz (far IR and millimeter regions) of 300–1500 um (0.3–1.0 THz). For all compositions, the refractive index in the IR varied from 2.107 to 2.436. The materials’ absorption coefficients were (0.06–6.67) ∙ 10-4 in the middle IR, which is lower compared to other halide materials known and indicates low optical loss. Finally, both single-crystals and two-phase ceramics showed a trend towards an increase in photoresistance with a rise of the AgI content in the AgCl0.25Br0.75 solid solution. After UV irradiation, the materials showed a decrease in transmission in the visible and middle IR (to 10 µm) with negligible loss at a wavelength of 10 µm or more. For a single crystal and two samples of ceramics with a composition of 20 mol. % AgI in AgCl0.25Br0.75, a comparison of properties was conducted in this study. Based on the comparison results, close but not identical values of the refractive indices, an increase in the absorption coefficient for ceramic materials, and a low photoresistance of the sample obtained from the mechanical mixture were revealed. The last two characteristics are associated with the high heterogeneity of two-phase ceramics based on a mechanical mixture, which leads to a deterioration in functional properties. These results prove high prospects for the use of these materials in fiber optics and photonics for medical technologies, thermography, and optoelectronics.

期刊介绍: The Journal covers the entire field of infrared physics and technology: theory, experiment, application, devices and instrumentation. Infrared'' is defined as covering the near, mid and far infrared (terahertz) regions from 0.75um (750nm) to 1mm (300GHz.) Submissions in the 300GHz to 100GHz region may be accepted at the editors discretion if their content is relevant to shorter wavelengths. Submissions must be primarily concerned with and directly relevant to this spectral region. Its core topics can be summarized as the generation, propagation and detection, of infrared radiation; the associated optics, materials and devices; and its use in all fields of science, industry, engineering and medicine. Infrared techniques occur in many different fields, notably spectroscopy and interferometry; material characterization and processing; atmospheric physics, astronomy and space research. Scientific aspects include lasers, quantum optics, quantum electronics, image processing and semiconductor physics. Some important applications are medical diagnostics and treatment, industrial inspection and environmental monitoring.
