WebMar 8, 2024 · Bleaching is when a material permanently changes its optical properties, typically because of a chemical reaction. In particular photobleaching is a reaction … WebExcited-state-absorption (ESA) process involves the sequential absorption of pump photons by a single lanthanide ion, owing to the ladder-like structure of a simple multilevel system. In a typical ESA process ( Fig. 9.1 a), transition from the ground state (E 0) to a metastable state (E 1) occurs after the absorption of one lower-energy photon.
