Bright photon upconversion on composite organic lanthanide molecules through localized thermal radiation. The Journal of Physical Chemistry Letters, 8(23), 5695-5699. doi:10.1021/acs.jpclett.7b02513 | Journal: | The Journal of Physical Chemistry Letters | Abstract: | Converting low-energy photons via thermal radiation can be a potential approach for utilizing infrared (IR) photons to improve photovoltaic efficiency. Lanthanide-containing materials have achieved great progress in IR-to-visible photon upconversion (UC). Herein, we first report bright photon, tunable wavelength UC through localized thermal radiation at the molecular scale with low excitation power density (<10 W/cm2) realized on lanthanide complexes of perfluorinated organic ligands. This is enabled by engineering the pathways of nonradiative de-excitation and energy transfer in a composite of ytterbium and terbium perfluoroimidodiphosphinates. The IR-excited thermal UC and wavelength control is realized through the terbium activators sensitized by the ytterbium sensitizers having high luminescence efficiency. The metallic molecular composite thus can be a potential energy material in the use of the IR solar spectrum for thermal photovoltaic applications. | URI: | https://hdl.handle.net/10356/140364 | ISSN: | 1948-7185 | DOI: | 10.1021/acs.jpclett.7b02513 | Schools: | School of Electrical and Electronic Engineering School of Physical and Mathematical Sciences |
