Visible Imaging of Incoherent 1200-nm Light via Triplet--Triplet Annihilation Upconversion
Pournima Narayanan, Rabeeya Hamid, Linda Pucurimay +13
Upconversion of low-energy photons to higher-energy photons provides an opportunity to surpass traditional limitations in fields such as 3D printing, photovoltaics, and photocataly…

All-passive upconversion of incoherent near-infrared light at intensities down to 10 W/cm
Rabeeya Hamid, Demeng Feng, Pournima Narayanan +10
Frequency upconversion, which converts low-energy photons into higher-energy ones, typically requires intense coherent illumination to drive nonlinear processes or the use of exter…
