In this Letter, CdSe and PbSe semiconductor nanocrystals are combined with molecular emitters (diphenylanthracene and rubrene) to upconvert photons in both the visible and the near-infrared spectral regions. Absorption of low energy photons by the nanocrystals is followed by energy transfer to the molecular triplet states, which then undergo triplet\u2013triplet annihilation to create high energy singlet states that emit upconverted light. By using conjugated organic ligands on the CdSe nanocrystals to form an energy cascade, the upconversion process could be enhanced by up to 3 orders of magnitude. The use of different combinations of nanocrystals and emitters shows that this platform has great flexibility in the choice of both excitation and emission wavelengths.<\/jats:p>","DOI":"10.1021\/acs.nanolett.5b02130","type":"journal-article","created":{"date-parts":[[2015,7,10]],"date-time":"2015-07-10T11:46:03Z","timestamp":1436528763000},"page":"5552-5557","source":"Crossref","is-referenced-by-count":341,"title":["Hybrid Molecule\u2013Nanocrystal Photon Upconversion\nAcross the Visible and Near-Infrared"],"prefix":"10.1021","volume":"15","author":[{"given":"Zhiyuan","family":"Huang","sequence":"first","affiliation":[{"name":"University of California Riverside , , ,","place":["Riverside, California, United States, 92521"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Li","sequence":"additional","affiliation":[{"name":"University of California Riverside , , ,","place":["Riverside, California, United States, 92521"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melika","family":"Mahboub","sequence":"additional","affiliation":[{"name":"University of California Riverside , , ,","place":["Riverside, California, United States, 92521"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kerry M.","family":"Hanson","sequence":"additional","affiliation":[{"name":"University of California Riverside , , ,","place":["Riverside, California, United States, 92521"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valerie M.","family":"Nichols","sequence":"additional","affiliation":[{"name":"University of California Riverside , , ,","place":["Riverside, California, United States, 92521"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hoang","family":"Le","sequence":"additional","affiliation":[{"name":"University of California Riverside , , ,","place":["Riverside, California, United States, 92521"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ming L.","family":"Tang","sequence":"additional","affiliation":[{"name":"University of California Riverside , , ,","place":["Riverside, California, United States, 92521"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher J.","family":"Bardeen","sequence":"additional","affiliation":[{"name":"University of California Riverside , , ,","place":["Riverside, California, United States, 92521"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2015,7,10]]},"reference":[{"key":"2026090121204848000_cit1","doi-asserted-by":"publisher","first-page":"1302","DOI":"10.1039\/C4CS00173G","article-title":"Upconverting Nanoparticles: a Versatile\nPlatform for Wide-Field Two-Photon Microscopy and Multi-Modal In Vivo\nImaging","volume":"44","author":"Park","year":"2015","journal-title":"Chem.
