Abstract
Doped, nanosize metal oxide particles have been shown to exhibit stimulated emission and continuous-wave laser action when energized appropriately, for example by electron beams. The doped particles are useful as solid state lasing devices and “laser paints”. Particles containing homogeneously distributed dopant atoms in concentrations greater than the thermodynamic solubility in the metal oxide matrix, and having in some circumstances, unusual oxidation states, have been produced.
