Abstract

The temperature dependences of luminescence in slip planes (111) of diamond plates containing nitrogen defects A and B1 upon excitation by a laser with a wavelength of 532 nm were investigated with the use of confocal scanning luminescence microscopy. The red glow of the diamond in the slip planes was dominated by the glow of the center with a zero phonon line (ZPL) of 656 nm at 290 K and the glow of the center with a zero phonon line of 701 nm at 80 K (i.e., spectra were different at different temperatures).
