Upconversion Spectrophotofluorometry [PDF]
, 2013 As the other chapters attest, sensitivity of fluorescent molecules to their local environment has created powerful tools in the study of molecular biology, particularly in the study of protein, DNA, and lipid dynamics. Surprisingly, even events faster than the nanosecond lifetimes of fluorophores are important in protein function, and in particular ...

Recharging Upconversion: Revealing Rubrene’s Replacement
, 2022 One of the major limitations of solid-state perovskite-sensitized photon upconversion to date is that the only annihilator successfully paired with the perovskite sensitizer has been rubrene, raising the question of whether this approach of triplet ...

Impact of energy-transfer-upconversion on performance in quasi-three-level solid-state lasers [PDF]
, 2009 Energy-transfer-upconversion (ETU) has a detrimental impact on performance in a number of different solid-state lasers [1]. ETU manifests itself as a reduction in the effective upper laser level lifetime leading reduced energy storage and increased ...

Photon Upconversion in Small Molecules
Molecules, 2022 Upconversion (UC) is a process that describes the emission of shorter-wavelength light compared to that of the excitation source. Thus, UC is also referred to as anti-Stokes emission because the excitation wavelength is longer than the emission wavelength. UC materials are used in many fields, from electronics to medicine.

Photochemical Upconversion in Solution: The Role of Oxygen and Magnetic Field Response
, 2023 Upconversion processes effectively convert two or more low energy photons into one higher energy photon, and have diverse applications in photovoltaics and biomedicine. Upconversion is generally spin-selective, and its magnetic field response can be used
