Solar-induced chlorophyll fluorescence (SIF) is a crucial indicator of vegetation photosynthesis, and in recent years, tower-based SIF measurements have become increasingly valuable in conjunction ...

The triplet state has a typical lifetime of microseconds and interacts with a target species, transferring energy ... the absorption from the transient triplet state, while laser-induced fluorescence ...

Edinburgh Instruments An emission spectrum may be utilized to distinguish emissive energy transitions in materials. Emission arises from the absorption of multiple low-energy 980 nm photons by many Yb ...
