摘要

(La, Sr)(Al, Ta) o3晶体经20.0 MeV C离子辐照，辐照量为1.0×10 15 ions/ cm2。利用卢瑟福后向散射(RBS)/通道光谱、硬度和弹性模量作为深度的连续函数，以及x射线衍射(XRD)分析了样品近表面的辐照损伤、硬度和结构变化。采用棱镜耦合和端面耦合的方法研究了不同退火条件下光波导性能的变化。考虑到低损耗波导结构在光电传感器中的潜在应用，将(La, Sr)(Al, Ta) o3样品的电学性能作为传感器的重要检测指标进行了研究。

Damage, waveguide and electrical properties in (La, Sr)(Al, Ta)O3 single crystal irradiated with carbon ions

The (La, Sr)(Al, Ta)O 3 crystal was irradiated via 20.0 MeV C ion with fluence of 1.0×10 15 ions/cm 2 . The Rutherford backscattering (RBS)/channeling spectra, the hardness and elastic modulus as continuous functions of the depth, and X-ray diffraction (XRD) are used to analyze the irradiation damage, hardness, and structural changes in the near-surface area of samples. Prism coupling and end-face coupling methods were used to study the changes of optical waveguide properties under different annealing conditions. Considering the potential applications of low-loss waveguide structure in photoelectric sensors, electrical properties of (La, Sr)(Al, Ta)O 3 samples were studied as an important detection indicator of sensors.
