Interference-enhanced infrared-to-visible upconversion in solid-state thin films sensitized by colloidal nanocrystals

Journal Article Wu, Mengfei ; Jean, Joel ; Bulović, Vladimir ; ... - Applied Physics Letters

Infrared-to-visible photon upconversion has potential applications in photovoltaics, sensing, and bioimaging. In this paper, we demonstrate a solid-state thin-film device that utilizes sensitized triplet-triplet exciton annihilation, converting infrared photons absorbed by colloidal lead sulfide nanocrystals (NCs) into visible photons emitted from a luminescent dopant in rubrene at low incident light intensities. A typical bilayer device consisting of a monolayer of NCs and a doped film of rubrene is limited by low infrared absorption in the thin NC film. Here, we augment the bilayer with an optical spacer layer and a silver-film back reflector, resulting in interference effects that enhance themore »« less

Nanocrystal-Sensitized Infrared-to-Visible Upconversion in a Microcavity under Subsolar Flux

Journal Article Wu, Mengfei ; Lin, Ting-An ; Tiepelt, Jan O. ; ... - Nano Letters

Infrared-to-visible photon upconversion could benefit applications such as photovoltaics, infrared sensing, and bioimaging. Solid-state upconversion based on triplet exciton annihilation sensitized by nanocrystals is one of the most promising approaches, albeit limited by relatively weak optical absorption. Here, we integrate the upconverting layers into a Fabry–Pérot microcavity with quality factor Q = 75. At the resonant wavelength λ = 980 nm, absorption increases 74-fold and we observe a 227-fold increase in the intensity of upconverted emission. The threshold excitation intensity is reduced by 2 orders of magnitude to a subsolar flux of 13 mW/ cm². We measure an external quantummore »« less

Solid-state infrared-to-visible upconversion sensitized by colloidal nanocrystals

Journal Article Wu, Mengfei ; Congreve, Daniel N. ; Wilson, Mark W. B. ; ... - Nature Photonics

Optical upconversion via sensitized triplet–triplet exciton annihilation converts incoherent low-energy photons to shorter wavelengths under modest excitation intensities1,2,3. Here, we report a solid-state thin film for infrared-to-visible upconversion that employs lead sulphide colloidal nanocrystals as a sensitizer. Upconversion is achieved from pump wavelengths beyond λ = 1 μm to emission at λ = 612 nm. When excited at λ = 808 nm, two excitons in the sensitizer are converted to one higher-energy state in the emitter at a yield of 1.2 ± 0.2%. Peak efficiency is attained at an absorbed intensity equivalent to less than one sun. We demonstrate thatmore »« less

Enhanced Near-Infrared-to-Visible Upconversion by Synthetic Control of PbS Nanocrystal Triplet Photosensitizers

Journal Article Huang, Zhiyuan ; Xu, Zihao ; Mahboub, Melika ; ... - Journal of the American Chemical Society

Photon upconversion employing semicon- ductor nanocrystals (NCs) makes use of their large and tunable absorption to harvest light in the near-infrared (NIR) wavelengths as well as their small gap between singlet and triplet excited states to reduce energy losses. In this work, we report the highest QY (11.8%) thus far for the conversion of NIR to yellow photons by improving the quality of the PbS NC. This high QY was achieved by using highly purified lead and thiourea precursors. This QY is 2.6 times higher than from NCs prepared with commercially available lead and sulfide precursors. Transient absorption spectroscopy revealsmore »« less
