Fluorescence Lifetimes and Dynamic Quenching

WebbQuenching is the process of rapidly cooling a material (usually a metal) in order to obtain desirable mechanical properties like increased strength and hardness. Most people think quenching is just dunking red-hot steel into a bucket of water, but materials scientists can quench in water, oil, liquid nitrogen, or even air. WebbFluorescence quenching refers to any process that decreases the fluorescence intensity of a sample. A variety of molecular interactions can result in quenching. These include excited-state reactions, molecular rearrangements, energy transfer, ground-state complex formation, and colli-sional quenching. WebbThe quench experiments indicate that the two boundaries have similar Clapeyron P-T slopes. Our in situ measurements indicate that the akimotoite-perovskite phase transition boundary has a much more negative slope than the postspinel transition boundary and the two boundaries would cross over at about 1160°C ( Figure 6 ). c s warehouse jobs
