char·ac·ter·is·tic ra·di·a·tion

monochromatic radiation that is produced when an electron is ejected from an atom and another takes its place by jumping from another shell; the energy of the emitted photon is the difference between that of the two shell positions. See: photoelectric effect.

char·ac·ter·is·tic ra·di·a·tion

(kar'ăk-tĕr-is'tik rā'dē-ā'shŭn)
When an incoming electron from the cathode stream that has enough energy to overcome the binding energy of electrons in the inner shells of the target material knocks the electron out of its shell, the outer electrons fall into the inner shell, giving up energy in the form of x-radiation. Produced at levels above 69.5 kV. This process leaves the atom ionized.

After substituting the [Zn.sup.2+] sites in ZnMo[O.sub.4], the rare-earth ions in the ZnMo[O.sub.4] crystal lattice can give off the characteristic emissions of the rare-earth dopants upon ultraviolet excitation.
It is known that the intensity of the characteristic emissions of [Eu.sup.3+] in host materials depends on the [Eu.sup.3+] concentration, but no much new insight can be provided by varying the concentration of [Eu.sup.3+] dopant except PL quenching at high doping concentration [4, 8].
Since ML glow curve shows the characteristic emission of [RE.sup.3+], this energy may be transferred nonradiatively to [RE.sup.3+] ions causing their excitation and subsequent deexcitation of excited [RE.sup.3+] ions.

These elements will be identified based on the characteristic emissions when exposed to sunlight.
Aluminium is often used as a base coat, this has been difficult to measure in the past as it has a very low atomic number, and the energy levels of its characteristic emissions are low.
Following X-irradiation and subsequent heating in the temperature interval 23-200[degrees]C, TL glow curves produced characteristic emissions near 75[degrees]C and 100[degrees]C from the crystalline and amorphous regions, respectively.
