4 cards from this section. Quick, good the night before a test.
Define fluorescence. How is it different from phosphorescence?
Consider the duration of light emission for both phenomena.
What is Stokes shift?
Think about how energy is related to wavelength.
What is fluorescence?
Think about what happens to a molecule after it absorbs light.
True or False: A higher quantum yield indicates more efficient fluorescence.
Consider what a value less than 1 means.
A fluorophore emits only 30% of the light it absorbs as fluorescence. If it absorbs 250 photons, how many photons are emitted?
How do you use percentages in calculations?
Given a measured intensity of 50 counts for a standard concentration of 10 mg/L, what would be the expected intensity for a concentration of 25 mg/L under the same conditions?
Consider how intensity proportionality works with concentration in a linear relationship.
