Upconversion-powered photoelectrochemistry

Chem. Commun., 2012
Upconversion photochemistry occurring between palladium(II) octaethylporphyrin (PdOEP, 1) and 9,10-diphenylanthracene (DPA, 2) in toluene successfully sensitizes nanostructured WO(3) photoanodes (E(g) = 2.7 eV) to sub-bandgap non-coherent green photons at low power density.

Photon upconversion devices

SPIE Proceedings, 2006
This paper presents our research and development effort in realizing and perfecting photon upconversion devices for wavelengths from 1.5 μm region to 0.87 μm. The basic idea is to integrate a 1.5-μm detector with a 0.87-μm light emitting diode (LED), connected in series. The detected photocurrent drives the LED, thereby achieving the upconversion.

Plasmon-Enhanced Upconversion

The Journal of Physical Chemistry Letters, 2014
Upconversion, the conversion of photons from lower to higher energies, is a process that promises applications ranging from high-efficiency photovoltaic and photocatalytic cells to background-free bioimaging and therapeutic probes. Existing upconverting materials, however, remain too inefficient for viable implementation.
