Ground state bleaching 意味
WebThe earliest TA spectra show two positive bands, one peaking at 535 nm with a distinct vibronic structure, and another with a maximum at about 360 nm and a broad shoulder. This second band is located on the low-energy side of an intense ground-state bleach around 340 nm. Weaker ground-state bleach features are also visible above 550 nm. http://www.chem.ucla.edu/dept/Faculty/schwartz/schwartz_pubs/JPC_98_4489_1994.pdf

WebFluorophores are molecules that, upon absorbing light energy, can reach an excited state, then emit light energy. The three-stage process of excitation, excited lifetime, and emission is called fluorescence. Fluorophores absorb a range of wavelengths of light energy, and also emit a range of wavelengths. Within these ranges are the excitation ... Bleaching of ground state refers to depletion of the ground state carriers to excited states. Stimulated emission follows the fluorescence spectrum of the molecule and is Stokes shifted relative to and often still overlaps with the bleach signal. This is a lasing effect (coherent emission) of the excited … See more In physics and physical chemistry, time-resolved spectroscopy is the study of dynamic processes in materials or chemical compounds by means of spectroscopic techniques. Most often, processes are studied after the … See more Time-resolved infrared (TRIR) spectroscopy also employs a two-pulse, "pump-probe" methodology.

WebQuenching refers to any process which decreases the fluorescence intensity of a given substance. A variety of processes can result in quenching, such as excited state reactions, energy transfer, complex-formation and collisional quenching. As a consequence, quenching is often heavily dependent on pressure and temperature.Molecular oxygen, iodide ions …
