We present a method for obtaining the average single-molecule biexciton lifetime from an ensemble of chromophores in solution. We apply this analysis to a series of core/shell CdSe/CdS quantum dot heterostructures with increasing shell thickness and

Publikováno v: Nano letters. 16(1)

The optimization of photoluminescence spectral linewidths in semiconductor nanocrystal preparations involves minimizing both the homogeneous and inhomogeneous contributions to the ensemble spectrum. Although the inhomogeneous contribution can be cont

Smoke oxidation kinetics for application to prediction of clean burn patterns

Autor: Craig L. Beyler, Andrew P. Beyler, Siamak Riahi, JudithAnn R. Hartman

Publikováno v: Fire and Materials. 36:177-184

SUMMARY Smoke deposition patterns are a potentially rich source of information concerning the behavior of a fire. Clean burn patterns are smoke-free areas where smoke deposits have been oxidized away. In order to predict the formation of clean burn p

Mechanisms of fluorescence enhancement in rare earth sol–gel glass containing Al3+

Autor: D.M. Boye, A.J. Silversmith, K. E. Arpino, Andrew P. Beyler, K.R. Hoffman

Publikováno v: Journal of Luminescence. 131:457-460

Analysis of glasses containing Eu and Tb dopants yields new insights about the role of Al 3+ co-doping in improving fluorescence yield of glasses containing rare earth (RE) dopants. Our work suggests that Al co-doping enhances fluorescence by two imp

Publikováno v: Nano letters. 14(12)

The brightness of nanoscale optical materials such as semiconductor nanocrystals is currently limited in high excitation flux applications by inefficient multiexciton fluorescence. We have devised a solution-phase photon correlation measurement that

Publikováno v: Chemical Society reviews. 43(4)

Prior to the advent of single-molecule fluorescence spectroscopy, many of the fundamental optical properties of colloidal semiconductor nanocrystal quantum dots were obscured by ensemble averaging over their inherent inhomogeneities. Single quantum d
