The absorption of ultraviolet radiation by diamond

摘要: The thinnest diamonds of the so-called ultraviolet opaque type have been shown to exhibit transmission upto 2240 A which is also limit for transparent type. In a diamond showing blue luminescence, five new absorption bands discovered first time in region below 2300 A. variation coefficient with wavelength typical blue-luminescent has determined 3030 A-2570 Finally, limits number obtained different photographic exposures and data correlated their luminescence mean infra-red 8 μ region.
