Abstract
The main up-conversion mechanisms of the anti-Stokes luminescence of rare-earth (TR3+) ions were considered, such as summation of photon energy through energy transfers, successive absorption of photons, cooperative sensitization, and cooperative luminescence. The analysis of the specific features of the up-conversion mechanisms was performed on the micro- and macroscopic levels. On the basis of the survey of literature data on the given themes, the general systematization of the mechanisms of up-conversion phenomena was obtained. The rate equations describing the populations of energy levels of TR3+ ions for the cases of system with activator and sensitizer and system without sensitizer are given in the general form. The photon avalanche effect is considered.
