摘要

本文研究了拉曼测量过程中激光(532 nm威尔第G线)加热对Bi12SiO20单晶部分分解的影响。分解的程度直接取决于激光处理的功率密度和持续时间，这是由声子拉曼光谱记录的。激光处理后，AFM测量记录了表面上额外的小球形岛屿。对辐照和未辐照样品的分析表明，透射光谱、x射线衍射(XRD)图、Verdet常数、磁光性能和吸收系数发生了显著变化。激光照射后获得的材料可以描述为由氧化铋和氧化硅基纳米物体(直径小于15 nm)组成的特定纳米复合材料，它们排列在Bi12SiO20基体中。

Effect of Laser Heating on Partial Decomposition of Bi12SiO20 (BSO) Single Crystal: Raman Study

The effect of laser (532 nm line of Verdi G) heating during the Raman measurements, on partial decomposition of Bi12SiO20 single crystal, was addressed in this study. The degree of decomposition directly depends on the power density and duration of the laser treatment, which are registered by the phonon Raman spectra. After laser treatment, AFM measurements register additional small spherical islands on the surface. Analysis performed on irradiated and unirradiated samples showed significant changes in transmission spectra, X-ray diffraction (XRD) pattern, Verdet constant, magneto-optical property, and absorption coefficient. The material obtained after laser irradiation can be described as specific nanocomposite consisting of bismuth oxide and silicon oxide-based nano-objects (dimensions below 15 nm in diameter), which are arranged in a matrix of Bi12SiO20.
