摘要：
Low temperature cathodoluminescence and photoluminescence measurements have been used to study radiative recombination processes in chemical vapor-deposited flame-grown diamond films that were nominally undoped, nitrogen- or boron-doped, and nitrogen + boron codoped. The crystalline qualities of the films were evaluated using the ratios of the intensities of the first-order Raman phonons of diamond and amorphous carbon as figures of merit. Steady state and time-resolved photoluminescence measurements performed for samples simultaneously doped with nitrogen and boron revealed a broad red emission band, with a maximum at 1.95 eV that appears to be nitrogen related.
