Abstract
Gamma-ray induced luminescence from various types of diamonds is investigated at room temperature. The diamonds are irradiated with gamma-ray of 1.17 and 1.33 MeV from a cobalt-60 source. The luminescence from micron-sized and bulk diamonds is observed with a peak at around 525 nm in the range from 400 nm to 850 nm. The main peak is attributed to the Ni related S center. For nano-sized diamond, the luminescence peak consisting of emission bands at 410 and 450 nm appears due to dislocation A-band and ND1 center. Observed luminescence suggests the possibility of the extended red emission in the 550–900 nm range from diamond dust induced by the electromagnetic waves such as gamma rays in outer space.
期刊介绍：
Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged.
A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions.
The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
