The first galvanoluminescence spectrum in the ultraviolet region obtained during anodization of high purity aluminum samples annealed at temperature above 525°C is presented. An intense broad peak with the maximum at about 31,900 cm(-1) is assigned to the transitions (some of them heretofore unobserved) between vibrational levels of the C(2)∏→X(2)Σ(+) spectral system of AlO, partly overlapped with the A(2)Σ(+)→X(2)∏ system of OH.
本文呈现了在高于 525°C 退火的高纯铝样品阳极氧化过程中首次获得的紫外区的第一份电致发光光谱。一个强烈的宽峰，其最大值约为 31900 cm(-1)，被分配给 C(2)∏→X(2)∑(+)光谱系统的 AlO 的振动能级之间的跃迁（其中一些迄今未被观察到），部分与 OH 的 A(2)∑(+)→X(2)∏系统重叠。
