Question

Fluorescent radiation produced by electrons depends on which of the following factors?

(a) Concentration of the photon

(b) Solubility of the sample

(c) Atomic number of the atoms

(d) Frequency of the radiation

I got this question during an online interview.

My question is based upon Sources of Background Radiation Fluorescence topic in portion X-Ray Diffraction of Solid State Chemistry

Answer 1

Right choice is (c) Atomic number of the atoms

Easiest explanation: The inner shell electrons are knocked out and thus fluorescent radiation is produced, in this method fluorescent radiation depends on the atomic number of the atoms in the sample relative to that of the target material.
