Color improvement of rubies by ion beam technique
© 2016 Elsevier B.V. Ion implantation technique has been used for improving the quality of natural ruby. The implantation was performed by using 90 keV N 2 -ion and 50 keV O-ion beams. Either kind of ion species could eliminate tiny inclusions in the ruby as observed from an optical microscope. The...
