摘要
On the basis of study on X-ray spectroscopic characteristics of diamond and its associated minerals, this paper, according to the difference between the two spectroscopic peak value bands and lightening intensities, explores the probability of introducing colour filter to attenuate the spectroscopic peak bands of associated minerals and enhance the resolution of diamond X-ray selection, and comparatively analyses,through experiment,the different selection effects produced by using different kinds of colour filters, finally deciding Chinese-built QB4 colour filter as the optimum selection colour filter in diamond X-ray selection.
