Enhancement of Fluorescence in a Solution
Fluorescence is the property of a substance to emit light of a longer wavelength than the excitation wavelength. The intensity of fluorescence depends on various parameters. In this question, we have to identify the parameters that enhance fluorescence in a solution. The correct answer is A, B, and D.
Molar Absorptivity of Fluorescent Molecule
Molar absorptivity is the measure of how strongly a substance absorbs light at a particular wavelength. It is a characteristic property of a substance. Higher molar absorptivity means the substance will absorb more light. The absorption of light increases the population of excited states of the fluorescent molecule. Therefore, higher molar absorptivity leads to more excited states, which in turn leads to enhanced fluorescence.
Intensity of Light Source
The intensity of the light source is another parameter that enhances fluorescence. When the intensity of light is increased, more photons are absorbed by the fluorescent molecule. This results in the production of more excited states, leading to enhanced fluorescence.
Concentration of Sample
The concentration of the sample affects the fluorescence intensity. At low concentrations, the number of fluorescent molecules is low, resulting in a low fluorescence signal. As the concentration increases, more fluorescent molecules are present, leading to enhanced fluorescence.
Dissolved Oxygen
Dissolved oxygen can quench the excited states of the fluorescent molecule. Therefore, the presence of dissolved oxygen can reduce the fluorescence intensity. Hence, the correct answer does not include dissolved oxygen.
Conclusion
In conclusion, the correct answer is A, B, and D. The molar absorptivity of the fluorescent molecule, the intensity of the light source, and the concentration of the sample all contribute to enhanced fluorescence. On the other hand, dissolved oxygen can reduce fluorescence intensity.
