Properties of two different sizes sub 100 nm FNDs. (a) Secondary electron images of 40 nm and 70 nm FNDs. (b) Size distributions of FND40 (left) and FND70 (right) were defined as the square root of the surface area of the diamonds as detected with secondary electrons as shown in A. (c) CL intensity. (d) The correlation of diamond size with CL intensity for FND70. Bar: 1 μm.
