Considering the following parameters with reference to the fluorescence of a solution: 1. Molar absorptivity of fluorescent molecule 2. Intensity of light source used for excitation 3. Dissolved oxygen The correct answer for the enhancement of fluorescence with the increase in these parameters is/are
(a)1 and 2
(b)2 and 3
(c)1 and 3
(d)3 only
Answer
Answer: A ✓ checked by 4AB · confidence high
Explanation
Fluorescence intensity ∝ I₀·ε·c·φ, so it rises with molar absorptivity (1) and source intensity (2); dissolved O₂ (3) quenches it.
