Lifetime orientation distributions of QEs around (a, d) rectangular, (b, e) cylinder, and (c, f) capsule gold and Si nanorods. The gold nanorods have wavelengths (a) 1,013, (b) 997, and (c) 946 nm, respectively. Four typical points are chosen: A (-70,0,0), B (-70,-10,0), C (-60,-20,0), and D (0,-20,0) nm. The lifetime orientation distributions of QEs around the rectangular, cylinder, capsule Si nanorods at wavelengths (d) 1,013, (e) 997, (f) 946 nm, respectively.
