The pulsed cathodoluminescence of synthetic HPHT diamonds excited by an electron pulse beam was studied at room temperature in air. The luminescence spectra of all diamonds contain a single non-elementary band; its maximum varies in the range from 490 to 504 nm. After turning off the electron beam, a second phosphorescence centered at 489 nm is observed. The kinetics of luminescence decay on the long-wavelength wing of the band at 520 nm was studied. Five characteristic times were obtained, three of which, tau_1=0.18, tau2=2 and tau3=18 ms, are related to the kinetics of the A-band, while the other two, tau4=190 ms and tau5=4.5 s, are related to the emission of C2 molecule. It is formed from interstitial carbon atoms under the action of high pressure and temperature during the synthesis of diamonds by the HPHT method and their embedding into cavities with tetrahedral and hexagonal symmetry. Keywords: pulsed cathodoluminescence, synthetic diamond, HPHT diamond, spectrum, interstitial carbon atom, kinetics, long-time emission.
