title = "Quantifying local density of optical states of nanorods by fluorescence lifetime imaging",
abstract = "Engineering of quantum emissions is regarded as the heart of nano-optics and photonics; local density of optical states (LDOS) around the quantum emitters are critical to engineer quantum emissions, thus detection of the LDOS will impact areas related to illumination, communication, energy, and even quantum-informatics. In this report, we demonstrated a far-field approach to detect and quantify the near-field LDOS of a nanorod via using CdTe quantum dots (QDs) tethered to the surface of nanorods as beacons for optical read-outs. The spontaneous decay of QD emission in the proximity of nanorod was used as a ruler for elucidating the LDOS. Our analysis indicates that the LDOS of the nanorod at its ends is 2.35 times greater than that at the waist. Our approach can be applied for further evaluation and elucidation of the optical states of other programmed nanostructures.",
