摘要
A CVD diamond material, substantially free of voids, has an average crystallite size greater than about 15 microns, a maximum intensity of the diamond Raman peak in counts/sec divided by the intensity of photoluminescence at 1270 cm.sup.-1 greater than about 3, a Raman sp.sup. 3 full width half maximum less than about 6 cm.sup.-1 and a diamond-to- graphite Raman ratio greater than about 25. The diamond material may also comprise carbon atoms with a C.sup.13 content less than 0.05 atomic %.
