The quenching effect
Webb6 mars 2024 · For convenience, we will define a ‘fluorescence lifetime in the absence of quencher’. τo = 1 k1 + k2. τo is the amount of time that it take for the fluorescence intensity to decay to 1 / e its initial value. A typical fluorescence decay curve is shown below in Figure 1 (the time axis is in units of nanoseconds). WebbY_2O_3:Ln (Ln = Tm or Eu) nano-powders with different particle sizes and various doping concentrations were prepared by using a combustion method.

The quenching effect
Did you know?
In materials science, quenching is the rapid cooling of a workpiece in water, oil, polymer, air, or other fluids to obtain certain material properties. A type of heat treating, quenching prevents undesired low-temperature processes, such as phase transformations, from occurring. It does this by reducing the window of time during which these undesired reactions are both thermodynamically favor… Quenching 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 … Visa mer Förster resonance energy transfer There are a few distinct mechanisms by which energy can be transferred non-radiatively (without absorption or emission of photons) between two dyes, a donor and an acceptor. Visa mer • Dark quencher, for use in molecular biology. • Förster resonance energy transfer, a phenomenon on which some quenching techniques rely Visa mer
