Abstract
Confocal fluorescence microscopy has been used to measure the three-di mensional distribution of the H3 color center produced in type IIa nat ural diamonds by 5 MeV He+ irradiation at a total fluence of 8 x 10(15 ) cm-2. The peak of the H3 emission occurs 16 mum below the surface of the irradiated side of the diamond, which is in fair agreement with t he peak of the vacancy distribution predicted by a Monte Carlo calcula tion (transport of ions in matter or TRIM). The H3 distribution is bro ader in the direction normal to the surface (10 mum full width at half maximum) than the TRIM calculation. This is attributed to diffusion o f vacancies caused by self-annealing during irradiation.
