Photoluminescence Spectroscopy
... In this experiment, the energy levels in a semiconductor quantum well structure are investigated using the technique of photoluminescence (PL). A laser is used to photoexcite electrons in a GaAs semiconductor and when they spontaneously de-excite they emit luminescence. The luminescence is analyzed ...

Quantum Numbers “Where are the Electrons?”
... Quantum numbers are used to describe atomic orbitals and the electrons in them. There are 4 quantum numbers: o The principal quantum number (n), indicates the main energy level occupied by the electron. n = a whole number such as 1, 2, 3, 4 n tells the distance from the nucleus and the energy of ...

Ionization
Ionization is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons to form ions, often in conjunction with other chemical changes. Ionization can result from the loss of an electron after collisions with sub atomic particles, collisions with other atoms, molecules and ions, or through the interaction with light. Heterolytic bond cleavage and heterolytic substitution reactions can result in the formation of ion pairs. Ionization can occur through radioactive decay by the internal conversion process, in which an excited nucleus transfers its energy to one of the inner-shell electrons causing it to be ejected.
