A study was made of the characteristics of the cathodoluminescence which arose from crystals with various dislocation configurations. It was found that D3 and D4 were observed along slip lines, while D1 and D2 were strong in the region where multiple slip lines intersected each other. It was shown that not only Lomer-Cottrell dislocations, but also jogs, acted as recombination centers for D1 and D2 luminescence. The spatial distributions of D1 and D2 luminescence were similar to each other; as were those of D3 and D4. The effect of hydrogenation upon the cathodoluminescence distribution was also investigated and, contrary to other reports, no evidence was found for the enhancement of D-line luminescence due to metal contamination.
