Abstract: For the first time a self-glowing blue-colored single crystal diamond (weighing 0.14 g) was synthesized by method of temperature gradient at high-pressure and high-temperature (TG HPHT) using starting precursor activated with carbon-14 in the form of BaCO 3. The total content of 14C in the crystal matrix is estimated 0.008 wt% or 1.8 MBq in total. The diamond emits intrinsic radioluminescence, which is visually observed in the dark. Basic properties of this diamond are discussed. [Display omitted] • Single crystal diamond activated with 14C was successfully grown for the first time. • Crystal has intensive self-glowing, which is easily visible in the dark by eyes. • The electric current generated by light conversion via photodetector was 14 nA. • The self-glowing spectrum is similar to the luminescence under irradiation from 99Tc.
