首次报道了爆轰法制备超分散金刚石材料的研究。在可见光中观察到一个发光带，并与人造和天然钻石中已知的中心发光带进行了类比，解释了它的一些结构特征。对超分散金刚石样品和表面经过不同化学处理的样品的光谱进行了比较，结果表明，超分散金刚石样品的光谱在很大程度上是由颗粒表面石墨化层的存在决定的。
The first study of materials based on ultradisperse diamond produced by detonation is reported. A luminescence band in the visible has been observed, and some of its structural features have been interpreted by analogy with the known luminescence bands of centers in synthetic and natural diamonds. A comparison of the spectra obtained from ultradisperse diamond samples with the surface modified by different chemical treatments suggests that their pattern is governed to a considerable extent by the presence of a graphitic layer on the grain surface.
