This work provides further step in considering artificial diamond crystals doped with beta-emitter 14C as chemically durable and environmentally friendly material to be applied as a core of nuclear electric photo-voltaic batteries. In order to investigate features of diamond radioluminescence the metallic radioactive technetium 99Tc and electron beam treatment have been used as external sources of beta-radiation simulating diamond self-glowing from admixture of 14C. Three types of commercially produced artificial diamonds have been applied: Ib, IIa and IIb. Intensive radioluminescence and cathodoluminescence have been observed for two diamond types: IIa and IIb, which can be suggested for further doping by 14C. It had been demonstrated that simulation of diamond self-glowing from 14C using 99Tc and electron beam were insufficiently different due to technical aspects of the experiment, not the difference in the excitation energy. Cathodoluminescence technique can be used in the future for the study of diamonds when optimizing it spectral properties.
