Phosphorescence and Stimulated Emission in Organic Molecules

Abstract

Stimulated emission of light has been demonstrated using aromatic organic molecules in a rigid glass matrix, e.g., acetophenone, benzaldehyde, benzophenone, α-bromonaphthalene, and pyrazine. This system is compared with the inorganic crystalline light masers. The experimental technique is described. Characteristic properties of the emitted light are given in detail and discussed. The conditions for achieving the stimulated emission threshold are described. The possibility of orienting molecules in a maser cell is proposed.
