Exciton Polaritons in Transition-Metal Dichalcogenides and Their Direct Excitation via Energy Transfer
(2015-08-28)Excitons, composite electron-hole quasiparticles, are known to play an important role in optoelectronic phenomena in many semiconducting materials. Recent experiments and theory indicate that the band-gap optics of the ... -
Local Field Effects for Spherical Quantum Dot Emitters in the Proximity of a Planar Dielectric Interface
(Optical Soc Amer, 2014-08-05)We use numerical solutions of macroscopic Maxwell's equations to study spontaneous emission rates of model spherical quantum dot (QD) emitters in the vicinity of a highly polarizable dielectric substrate. It is demonstrated ... -
Energy Transfer from Colloidal Nanocrystals into Si Substrates Studied via Photoluminescence Photon Counts and Decay Kinetics
(2013-08-16)We use time-resolved photoluminescence (PL) kinetics and PL intensity measurements to study the decay of photoexcitations in colloidal CdSe/ZnS nanocrystals grafted on SiO₂ - Si substrates with a wide range of the SiO₂ ...
