Dynamic lattice distortions driven by surface trapping in semiconductor nanocrystals
Burak Guzelturk, Benjamin L. Cotts, Dipti Jasrasaria +26
Nonradiative processes limit optoelectronic functionality of nanocrystals and curb their device performance. Nevertheless, the dynamic structural origins of nonradiative relaxation…
Bright sub-20 nm cathodoluminescent nanoprobes for multicolor electron microscopy
Maxim B. Prigozhin, Peter C. Maurer, Alexandra M. Courtis +18
Electron microscopy (EM) has been instrumental in our understanding of biological systems ranging from subcellular structures to complex organisms. Although EM reveals cellular mor…
Upconverting Core-Shell Nanocrystals with High Quantum Yield under Low Irradiance: On the Role of Isotropic and Thick Shells
Stefan Fischer, Noah J. J. Johnson, Jothirmayanantham Pichaandi +2
Colloidal upconverter nanocrystals (UCNCs) that convert near-infrared photons to higher energies are promising for applications ranging from life sciences to solar energy harvestin…
Plasmon enhanced upconversion luminescence near gold nanoparticles - Simulation and analysis of the interactions
Stefan Fischer, Florian Hallermann, Toni Eichelkraut +6
We investigate plasmon resonances in gold nanoparticles to enhance the quantum yield of upconverting materials. For this purpose, we use a rate equation model that describes the up…
Modeling upconversion of erbium doped microcrystals based on experimentally determined Einstein coefficients
S. Fischer, H. Steinkemper, P. Löper +2
Upconversion of infrared photons is a promising possibility to enhance solar cell efficiency by producing electricity from otherwise unused sub-band-gap photons. We present a rate…
