Refractive indices of metastable and amorphous phases in Ne~+-ion irradiated magnesium-aluminate spinel

摘要

Single-crystal MgAl_2O_4 subjected to 180 keV Ne~+-ion irradiation to fluences of (1, 5, and 10) ×10~20 ions/m~2. The metastable and amorphous phases induced by irradiation were studied using transmission electron microscopy (TEM) and optical transmission spectroscopy. The thicknesses of implantation-induced layer structures were obtained from TEM observations.
