摘要

本文研究了能量为 30 keV 的电子辐照对加入 0.1 至 10 wt.% 的 nY2O3 纳米粒子改性的微米级 mZnO 粉末的漫反射光谱和太阳辐照综合吸收系数的影响。纳米粒子的最佳含量为 3 wt.%，此时改性粉末的漫反射光谱和综合吸收系数比初始粉末低 1.41 倍。研究表明，在粉末辐照过程中形成的自由电子对粉末降解的影响最大。

Radiation Resistance of Optical Nanopowder Modified by Y2O3 Particles

The paper studies the electron irradiation at an energy of 30 keV affecting the diffuse-reflectance spectra and integrated absorption coefficient of solar irradiance of the micron-sized mZnO powder modified by adding nY₂O₃ nanoparticles in the amount of 0.1 to 10 wt.%. The best content of nanoparticles is found to be 3 wt.%, when the diffuse-reflectance spectra and the integrated absorption coefficient of the modified powder are 1.41 times lower than in the initial powder. It is shown that free electrons forming during the powder irradiation, make the highest contribution to the powder degradation.
